Status of this Memo
|

|
|
||||||
|

This memo provides information for the Internet community. This memo

Abstract
|
||||||
|
|
||||||
|
This document specifies a protocol for performing encapsulation of an
|
||||||
|
arbitrary network layer protocol over another arbitrary network layer
|
||||||
|
protocol.
|
||||||
|
|
||||||
|
Introduction
|
||||||
|
|
||||||
|
A number of different proposals [RFC 1234, RFC 1226] currently exist
|
||||||
|
for the encapsulation of one protocol over another protocol. Other
|
||||||
|
types of encapsulations [RFC 1241, SDRP, RFC 1479] have been proposed
|
||||||
|
for transporting IP over IP for policy purposes. This memo describes
|
||||||
|
a protocol which is very similar to, but is more general than, the
|
||||||
|
above proposals. In attempting to be more general, many protocol
|
||||||
|
specific nuances have been ignored. The result is that this proposal
|
||||||
|
is may be less suitable for a situation where a specific "X over Y"
|
||||||
|
encapsulation has been described. It is the attempt of this protocol
|
||||||
|
to provide a simple, general purpose mechanism which is reduces the
|
||||||
|
problem of encapsulation from its current O(n^2) problem to a more
|
||||||
|
manageable state. This proposal also attempts to provide a
|
||||||
|
lightweight encapsulation for use in policy based routing. This memo
|
||||||
|
explicitly does not address the issue of when a packet should be
|
||||||
|
encapsulated. This memo acknowledges, but does not address problems
|
||||||
|
with mutual encapsulation [RFC 1326].
|
||||||
|
|
||||||
|
In the most general case, a system has a packet that needs to be
|
||||||
|
encapsulated and routed. We will call this the payload packet. The
|
||||||
|
payload is first encapsulated in a GRE packet, which possibly also
|
||||||
|
includes a route. The resulting GRE packet can then be encapsulated
|
||||||
|
in some other protocol and then forwarded. We will call this outer
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||

RFC 1701 Generic Routing Encapsulation (GRE) October 1994
|
||||||
|
|

|
protocol the delivery protocol. The algorithms for processing this
|
||||||
|
packet are discussed later.
|
||||||
|
|
||||||
|
Overall packet
|
||||||
|
|
||||||
|
The entire encapsulated packet would then have the form:

Flags and version (2 octets)
|
||||||
|
|
||||||
|
The GRE flags are encoded in the first two octets. Bit 0 is the
|
||||||
|
most significant bit, bit 15 is the least significant bit. Bits
|
||||||
|
13 through 15 are reserved for the Version field. Bits 5 through
|
||||||
|
12 are reserved for future use and MUST be transmitted as zero.

|
||||||
|
|
||||||
|
|
||||||
|
Checksum Present (bit 0)
|
||||||
|
|
||||||
|
If the Checksum Present bit is set to 1, then the Checksum field
|
||||||
|
is present and contains valid information.
|
||||||
|
|
||||||
|
If either the Checksum Present bit or the Routing Present bit are
|
||||||
|
set, BOTH the Checksum and Offset fields are present in the GRE
|
||||||
|
packet.
|
||||||
|
|
||||||
|
Routing Present (bit 1)
|
||||||
|
|
||||||
|
If the Routing Present bit is set to 1, then it indicates that the
|
||||||
|
Offset and Routing fields are present and contain valid
|
||||||
|
information.
|
||||||
|
|
||||||
|
If either the Checksum Present bit or the Routing Present bit are
|
||||||
|
set, BOTH the Checksum and Offset fields are present in the GRE
|
||||||
|
packet.
|
||||||
|
|
||||||
|
Key Present (bit 2)
|
||||||
|
|
||||||
|
If the Key Present bit is set to 1, then it indicates that the Key
|
||||||
|
field is present in the GRE header. Otherwise, the Key field is
|
||||||
|
not present in the GRE header.
|
||||||
|
|
||||||
|
Sequence Number Present (bit 3)
|
||||||
|
|
||||||
|
If the Sequence Number Present bit is set to 1, then it indicates
|
||||||
|
that the Sequence Number field is present. Otherwise, the
|
||||||
|
Sequence Number field is not present in the GRE header.
|
||||||
|
|
||||||
|
Strict Source Route (bit 4)
|
||||||
|
|
||||||
|
The meaning of the Strict Source route bit is defined in other
|
||||||
|
documents. It is recommended that this bit only be set to 1 if
|
||||||
|
all of the the Routing Information consists of Strict Source
|
||||||
|
Routes.
|
||||||
|
|
||||||
|
Recursion Control (bits 5-7)
|
||||||
|
|
||||||
|
Recursion control contains a three bit unsigned integer which
|
||||||
|
contains the number of additional encapsulations which are
|
||||||
|
permissible. This SHOULD default to zero.
|
||||||
|
|
||||||
|
Version Number (bits 13-15)
|
||||||
|
|
||||||
|
The Version Number field MUST contain the value 0. Other values
|
||||||
|
are outside of the scope of this document.

RFC 1701 Generic Routing Encapsulation (GRE) October 1994
|
||||||
|
|
||||||
|
|
||||||
|
Protocol Type (2 octets)
|
||||||
|
|
||||||
|
The Protocol Type field contains the protocol type of the payload
|
||||||
|
packet. In general, the value will be the Ethernet protocol type
|
||||||
|
field for the packet. Currently defined protocol types are listed
|
||||||
|
below. Additional values may be defined in other documents.
|
||||||
|
|
||||||
|
Offset (2 octets)
|
||||||
|
|
||||||
|
The offset field indicates the octet offset from the start of the
|
||||||
|
Routing field to the first octet of the active Source Route Entry
|
||||||
|
to be examined. This field is present if the Routing Present or
|
||||||
|
the Checksum Present bit is set to 1, and contains valid
|
||||||
|
information only if the Routing Present bit is set to 1.
|
||||||
|
|
||||||
|
Checksum (2 octets)
|
||||||
|
|
||||||
|
The Checksum field contains the IP (one's complement) checksum of
|
||||||
|
the GRE header and the payload packet. This field is present if
|
||||||
|
the Routing Present or the Checksum Present bit is set to 1, and
|
||||||
|
contains valid information only if the Checksum Present bit is set
|
||||||
|
to 1.
|
||||||
|
|
||||||
|
Key (4 octets)
|
||||||
|
|
||||||
|
The Key field contains a four octet number which was inserted by
|
||||||
|
the encapsulator. It may be used by the receiver to authenticate
|
||||||
|
the source of the packet. The techniques for determining
|
||||||
|
authenticity are outside of the scope of this document. The Key
|
||||||
|
field is only present if the Key Present field is set to 1.
|
||||||
|
|
||||||
|
Sequence Number (4 octets)
|
||||||
|
|
||||||
|
The Sequence Number field contains an unsigned 32 bit integer
|
||||||
|
which is inserted by the encapsulator. It may be used by the
|
||||||
|
receiver to establish the order in which packets have been
|
||||||
|
transmitted from the encapsulator to the receiver. The exact
|
||||||
|
algorithms for the generation of the Sequence Number and the
|
||||||
|
semantics of their reception is outside of the scope of this

RFC 1701 Generic Routing Encapsulation (GRE) October 1994
|
||||||
|
|
||||||
|
|
||||||
|
The Routing field is a list of Source Route Entries (SREs). Each
|
||||||
|
SRE has the form:
|
||||||
|
|
||||||
|
0 1 2 3
|
||||||
|
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
|
||||||
|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|
||||||
|
| Address Family | SRE Offset | SRE Length |
|
||||||
|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|
||||||
|
| Routing Information ...
|
||||||
|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|
||||||
|
|
||||||
|
The routing field is terminated with a "NULL" SRE containing an
|
||||||
|
address family of type 0x0000 and a length of 0.
|
||||||
|
|
||||||
|
Address Family (2 octets)
|
||||||
|
|
||||||
|
The Address Family field contains a two octet value which indicates
|
||||||
|
the syntax and semantics of the Routing Information field. The
|
||||||
|
values for this field and the corresponding syntax and semantics for
|
||||||
|
Routing Information are defined in other documents.
|
||||||
|
|
||||||
|
SRE Offset (1 octet)
|
||||||
|
|
||||||
|
The SRE Offset field indicates the octet offset from the start of the
|
||||||
|
Routing Information field to the first octet of the active entry in
|
||||||
|
Source Route Entry to be examined.
|
||||||
|
|
||||||
|
SRE Length (1 octet)
|
||||||
|
|
||||||
|
The SRE Length field contains the number of octets in the SRE. If
|
||||||
|
the SRE Length is 0, this indicates this is the last SRE in the
|
||||||
|
Routing field.
|
||||||
|
|
||||||
|
Routing Information (variable)
|
||||||
|
|
||||||
|
The Routing Information field contains data which may be used in
|
||||||
|
routing this packet. The exact semantics of this field is defined in
|
||||||
|
other documents.
|
||||||
|
|
||||||
|
Forwarding of GRE packets
|
||||||
|
|
||||||
|
Normally, a system which is forwarding delivery layer packets will
|
||||||
|
not differentiate GRE packets from other packets in any way.
|
||||||
|
However, a GRE packet may be received by a system. In this case, the
|
||||||
|
system should use some delivery-specific means to determine that this
|
||||||
|
is a GRE packet. Once this is determined, the Key, Sequence Number
|
||||||
|
and Checksum fields if they contain valid information as indicated by
|
||||||
|
the corresponding flags may be checked. If the Routing Present bit
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|

|
RFC 1701 Generic Routing Encapsulation (GRE) October 1994
|
||||||
|
|
||||||
|
|
||||||
|
is set to 1, then the Address Family field should be checked to
|
||||||
|
determine the semantics and use of the SRE Length, SRE Offset and
|
||||||
|
Routing Information fields. The exact semantics for processing a SRE
|
||||||
|
for each Address Family is defined in other documents.
|
||||||
|
|
||||||
|
Once all SREs have been processed, then the source route is complete,
|
||||||
|
the GRE header should be removed, the payload's TTL MUST be
|
||||||
|
decremented (if one exists) and the payload packet should be
|
||||||
|
forwarded as a normal packet. The exact forwarding method depends on
|
||||||
|
the Protocol Type field.
|
||||||
|
|
||||||
|
Current List of Protocol Types
|
||||||
|
|
||||||
|
The following are currently assigned protocol types for GRE. Future
|
||||||
|
protocol types must be taken from DIX ethernet encoding. For
|
||||||
|
historical reasons, a number of other values have been used for some
|
||||||
|
protocols. The following table of values MUST be used to identify
|
||||||
|
the following protocols:

Status of this Memo

This memo provides information for the Internet community. This memo
|
||||||

does not specify an Internet standard of any kind. Distribution of

||||||
|
Introduction
|
||||||
|
|
||||||
|
In an earlier memo [RFC 1701], we described GRE, a mechanism for
|
||||||
|
encapsulating arbitrary packets within an arbitrary transport
|
||||||
|
protocol. This is a companion memo which describes the use of GRE
|
||||||
|
with IP. This memo addresses the case of using IP as the delivery
|
||||||
|
protocol or the payload protocol and the special case of IP as both
|
||||||
|
the delivery and payload. This memo also describes using IP
|
||||||
|
addresses and autonomous system numbers as part of a GRE source
|
||||||
|
route.
|
||||||
|
|
||||||
|
IP as a delivery protocol
|
||||||
|
|
||||||
|
GRE packets which are encapsulated within IP will use IP protocol
|
||||||
|
type 47.
|
||||||
|
|
||||||
|
IP as a payload protocol
|
||||||
|
|
||||||
|
IP packets will be encapsulated with a Protocol Type field of 0x800.
|
||||||
|
|
||||||
|
For the Address Family value of 0x800, the Routing Information field
|
||||||
|
will consist of a list of IP addresses and indicates an IP source
|
||||||
|
route. The first octet of the Routing Information field constitute a
|
||||||
|
8 bit integer offset from the start of the Source Route Entry (SRE),
|
||||||
|
called the SRE Offset. The SRE Offset indicates the first octet of
|
||||||
|
the next IP address. The SRE Length field consists of the total
|
||||||
|
length of the IP Address List in octets.

||||||

|
For the Address Family value of 0xfffe, the Routing Information field
|
||||||
|
will consist of a list of Autonomous System numbers and indicates an
|
||||||
|
AS source route. The third octet of the Routing Information field
|
||||||
|
contains an 8 bit unsigned integer offset from the start of the
|
||||||
|
Source Route Entry (SRE), called the SRE Offset. The SRE Offset
|
||||||
|
indicates the first octet of the next AS number. THe SRE Length
|
||||||
|
field consists of the total length of the AS Number list in octets.

IP as both delivery and payload protocol
|
||||||
|
|
||||||
|
When IP is encapsulated in IP, the TTL, TOS, and IP security options
|
||||||
|
MAY be copied from the payload packet into the same fields in the
|
||||||
|
delivery packet. The payload packet's TTL MUST be decremented when
|
||||||
|
the packet is decapsulated to insure that no packet lives forever.
|
||||||
|
|
||||||
|
IP source routes
|
||||||
|
|
||||||
|
When a system is processing a SRE with an Address Family indicating
|
||||||
|
an IP source route, it MUST use the SRE Offset to determine the next
|
||||||
|
destination IP address. If the next IP destination is this system,
|
||||||
|
the SRE Offset field should be increased by four (the size of an IP
|
||||||
|
address). If the SRE Offset is equal to the SRE Length in this SRE,
|
||||||
|
then the Offset field in the GRE header should be adjusted to point
|
||||||
|
to the next SRE (if any). This should be repeated until the next IP
|
||||||
|
destination is not this system or until the entire SRE has been
|
||||||
|
processed.
|
||||||
|
|
||||||
|
If the source route is incomplete, then the Strict Source Route bit
|
||||||
|
is checked. If the source route is a strict source route and the
|
||||||
|
next IP destination is NOT an adjacent system, the packet MUST be
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|

||||||
|
RFC 1702 GRE over IPv4 networks October 1994
|
||||||
|
|
||||||
|
|
||||||
|
dropped. Otherwise, the system should use the IP address indicated
|
||||||
|
by the Offset field to replace the destination address in the
|
||||||
|
delivery header and forward the packet.
|
||||||
|
|
||||||
|
Autonomous system source routes
|
||||||
|
|
||||||
|
When a system is processing a SRE with an Address Family indicating
|
||||||
|
an AS source route, it MUST use the SRE Offset field to determine the
|
||||||
|
next autonomous system. If the next autonomous system is the local
|
||||||
|
autonomous system, the SRE Offset field should be increased by two
|
||||||
|
(the size of an autonomous system number). If the SRE Offset is
|
||||||
|
equal to the SRE Length in this SRE, then the Offset field in the GRE
|
||||||
|
header should be adjusted to point to the next SRE (if any). This
|
||||||
|
should be repeated until the next autonomous system number is not
|
||||||
|
equal to the local autonomous system number or until the entire SRE
|
||||||
|
has been processed.
|
||||||
|
|
||||||
|
If the source route is incomplete, then the Strict Source Route bit
|
||||||
|
is checked. If the source route is a strict source route and the
|
||||||
|
next autonomous system is NOT an adjacent autonomous system, the
|
||||||
|
packet should be dropped. Otherwise, the system should use the
|
||||||
|
autonomous system number indicated by the SRE Offset field to replace
|
||||||
|
the destination address in the delivery header and forward the
|
||||||
|
packet. The exact mechanism for determining the next delivery
|
||||||
|
destination address given the AS number is outside of the scope of
|
||||||
|
this document.

Key words for use in RFCs to Indicate Requirement Levels
|
||||||
|
|
||||||
|
Status of this Memo
|
||||||
|
|
||||||
|
This document specifies an Internet Best Current Practices for the
|
||||||
|
Internet Community, and requests discussion and suggestions for
|
||||||
|
improvements. Distribution of this memo is unlimited.
|
||||||
|
|
||||||
|
Abstract
|
||||||
|
|
||||||
|
In many standards track documents several words are used to signify
|
||||||
|
the requirements in the specification. These words are often
|
||||||
|
capitalized. This document defines these words as they should be
|
||||||
|
interpreted in IETF documents. Authors who follow these guidelines
|
||||||
|
should incorporate this phrase near the beginning of their document:
|
||||||
|
|
||||||
|
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
|
||||||
|
NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and
|
||||||
|
"OPTIONAL" in this document are to be interpreted as described in
|
||||||
|
RFC 2119.
|
||||||
|
|
||||||
|
Note that the force of these words is modified by the requirement
|
||||||
|
level of the document in which they are used.
|
||||||
|
|
||||||
|
1. MUST This word, or the terms "REQUIRED" or "SHALL", mean that the
|
||||||
|
definition is an absolute requirement of the specification.
|
||||||
|
|
||||||
|
2. MUST NOT This phrase, or the phrase "SHALL NOT", mean that the
|
||||||
|
definition is an absolute prohibition of the specification.
|
||||||
|
|
||||||
|
3. SHOULD This word, or the adjective "RECOMMENDED", mean that there
|
||||||
|
may exist valid reasons in particular circumstances to ignore a
|
||||||
|
particular item, but the full implications must be understood and
|
||||||
|
carefully weighed before choosing a different course.
|
||||||
|
|
||||||
|
4. SHOULD NOT This phrase, or the phrase "NOT RECOMMENDED" mean that
|
||||||
|
there may exist valid reasons in particular circumstances when the
|
||||||
|
particular behavior is acceptable or even useful, but the full
|
||||||
|
implications should be understood and the case carefully weighed
|
||||||
|
before implementing any behavior described with this label.

||||||

|
||||||
|
RFC 2119 RFC Key Words March 1997
|
||||||
|
|
||||||
|
|
||||||
|
5. MAY This word, or the adjective "OPTIONAL", mean that an item is
|
||||||
|
truly optional. One vendor may choose to include the item because a
|
||||||
|
particular marketplace requires it or because the vendor feels that
|
||||||
|
it enhances the product while another vendor may omit the same item.
|
||||||
|
An implementation which does not include a particular option MUST be
|
||||||
|
prepared to interoperate with another implementation which does
|
||||||
|
include the option, though perhaps with reduced functionality. In the
|
||||||
|
same vein an implementation which does include a particular option
|
||||||
|
MUST be prepared to interoperate with another implementation which
|
||||||
|
does not include the option (except, of course, for the feature the
|
||||||
|
option provides.)
|
||||||
|
|
||||||
|
6. Guidance in the use of these Imperatives
|
||||||
|
|
||||||
|
Imperatives of the type defined in this memo must be used with care
|
||||||
|
and sparingly. In particular, they MUST only be used where it is
|
||||||
|
actually required for interoperation or to limit behavior which has
|
||||||
|
potential for causing harm (e.g., limiting retransmisssions) For
|
||||||
|
example, they must not be used to try to impose a particular method
|
||||||
|
on implementors where the method is not required for
|
||||||
|
interoperability.
|
||||||
|
|
||||||
|
7. Security Considerations
|
||||||
|
|
||||||
|
These terms are frequently used to specify behavior with security
|
||||||
|
implications. The effects on security of not implementing a MUST or
|
||||||
|
SHOULD, or doing something the specification says MUST NOT or SHOULD
|
||||||
|
NOT be done may be very subtle. Document authors should take the time
|
||||||
|
to elaborate the security implications of not following
|
||||||
|
recommendations or requirements as most implementors will not have
|
||||||
|
had the benefit of the experience and discussion that produced the
|
||||||
|
specification.

||||||
|
|
||||||
|

The definitions of these terms are an amalgam of definitions taken
|
||||||
|
from a number of RFCs. In addition, suggestions have been

||||||
|
incorporated from a number of people including Robert Ullmann, Thomas
|
||||||
|
Narten, Neal McBurnett, and Robert Elz.

Abstract
|
||||||
|
|
||||||
|
This document specifies a protocol for encapsulation of an arbitrary
|
||||||
|
network layer protocol over another arbitrary network layer protocol.
|
||||||
|
|
||||||
|
1. Introduction
|
||||||
|
|
||||||
|
A number of different proposals [RFC1234, RFC1226] currently exist
|
||||||
|
for the encapsulation of one protocol over another protocol. Other
|
||||||
|
types of encapsulations [RFC1241, RFC1479] have been proposed for
|
||||||
|
transporting IP over IP for policy purposes. This memo describes a
|
||||||
|
protocol which is very similar to, but is more general than, the
|
||||||
|
above proposals. In attempting to be more general, many protocol
|
||||||
|
specific nuances have been ignored. The result is that this proposal
|
||||||
|
may be less suitable for a situation where a specific "X over Y"
|
||||||
|
encapsulation has been described. It is the attempt of this protocol
|
||||||
|
to provide a simple, general purpose mechanism which reduces the
|
||||||
|
problem of encapsulation from its current O(n^2) size to a more
|
||||||
|
manageable size. This memo purposely does not address the issue of
|
||||||
|
when a packet should be encapsulated. This memo acknowledges, but
|
||||||
|
does not address problems such as mutual encapsulation [RFC1326].
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Farinacci, et al. Standards Track [Page 1]
|
||||||
|
|
||||||
|
RFC 2784 Generic Routing Encapsulation March 2000
|
||||||
|
|
||||||
|
|
||||||
|
In the most general case, a system has a packet that needs to be
|
||||||
|
encapsulated and delivered to some destination. We will call this
|
||||||
|
the payload packet. The payload is first encapsulated in a GRE
|
||||||
|
packet. The resulting GRE packet can then be encapsulated in some
|
||||||
|
other protocol and then forwarded. We will call this outer protocol
|
||||||
|
the delivery protocol. The algorithms for processing this packet are
|
||||||
|
discussed later.
|
||||||
|
|
||||||
|
Finally this specification describes the intersection of GRE
|
||||||
|
currently deployed by multiple vendors.
|
||||||
|
|
||||||
|
The keywords MUST, MUST NOT, MAY, OPTIONAL, REQUIRED, RECOMMENDED,
|
||||||
|
SHALL, SHALL NOT, SHOULD, SHOULD NOT are to be interpreted as defined
|
||||||
|
in RFC 2119 [RFC2119].
|
||||||
|
|
||||||
|
2. Structure of a GRE Encapsulated Packet
|
||||||
|
|
||||||
|
A GRE encapsulated packet has the form:
|
||||||
|
|
||||||
|
---------------------------------
|
||||||
|
| |
|
||||||
|
| Delivery Header |
|
||||||
|
| |
|
||||||
|
---------------------------------
|
||||||
|
| |
|
||||||
|
| GRE Header |
|
||||||
|
| |
|
||||||
|
---------------------------------
|
||||||
|
| |
|
||||||
|
| Payload packet |
|
||||||
|
| |
|
||||||
|
---------------------------------
|
||||||
|
|
||||||
|
This specification is generally concerned with the structure of the
|
||||||
|
GRE header, although special consideration is given to some of the
|
||||||
|
issues surrounding IPv4 payloads.
|
||||||
|
|
||||||
|
2.1. GRE Header
|
||||||
|
|
||||||
|
The GRE packet header has the form:
|
||||||
|
|
||||||
|
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

|
||||||
|
RFC 2784 Generic Routing Encapsulation March 2000
|
||||||
|
|
||||||
|
|
||||||
|
2.2. Checksum Present (bit 0)
|
||||||
|
|
||||||
|
If the Checksum Present bit is set to one, then the Checksum and the
|
||||||
|
Reserved1 fields are present and the Checksum field contains valid
|
||||||
|
information. Note that a compliant implementation MUST accept and
|
||||||
|
process this field.
|
||||||
|
|
||||||
|
2.3. Reserved0 (bits 1-12)
|
||||||
|
|
||||||
|
A receiver MUST discard a packet where any of bits 1-5 are non-zero,
|
||||||
|
unless that receiver implements RFC 1701. Bits 6-12 are reserved for
|
||||||
|
future use. These bits MUST be sent as zero and MUST be ignored on
|
||||||
|
receipt.
|
||||||
|
|
||||||
|
2.3.1. Version Number (bits 13-15)
|
||||||
|
|
||||||
|
The Version Number field MUST contain the value zero.
|
||||||
|
|
||||||
|
2.4. Protocol Type (2 octets)
|
||||||
|
|
||||||
|
The Protocol Type field contains the protocol type of the payload
|
||||||
|
packet. These Protocol Types are defined in [RFC1700] as "ETHER
|
||||||
|
TYPES" and in [ETYPES]. An implementation receiving a packet
|
||||||
|
containing a Protocol Type which is not listed in [RFC1700] or
|
||||||
|
[ETYPES] SHOULD discard the packet.
|
||||||
|
|
||||||
|
2.5. Checksum (2 octets)
|
||||||
|
|
||||||
|
The Checksum field contains the IP (one's complement) checksum sum of
|
||||||
|
the all the 16 bit words in the GRE header and the payload packet.
|
||||||
|
For purposes of computing the checksum, the value of the checksum
|
||||||
|
field is zero. This field is present only if the Checksum Present bit
|
||||||
|
is set to one.
|
||||||
|
|
||||||
|
2.6. Reserved1 (2 octets)
|
||||||
|
|
||||||
|
The Reserved1 field is reserved for future use, and if present, MUST
|
||||||
|
be transmitted as zero. The Reserved1 field is present only when the
|
||||||
|
Checksum field is present (that is, Checksum Present bit is set to
|
||||||
|
one).
|
||||||
|
|
||||||
|
3. IPv4 as a Payload
|
||||||
|
|
||||||
|
When IPv4 is being carried as the GRE payload, the Protocol Type
|
||||||
|
field MUST be set to 0x800.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Farinacci, et al. Standards Track [Page 3]

|
||||||
|
RFC 2784 Generic Routing Encapsulation March 2000
|
||||||
|
|
||||||
|
|
||||||
|
3.1. Forwarding Decapsulated IPv4 Payload Packets
|
||||||
|
|
||||||
|
When a tunnel endpoint decapsulates a GRE packet which has an IPv4
|
||||||
|
packet as the payload, the destination address in the IPv4 payload
|
||||||
|
packet header MUST be used to forward the packet and the TTL of the
|
||||||
|
payload packet MUST be decremented. Care should be taken when
|
||||||
|
forwarding such a packet, since if the destination address of the
|
||||||
|
payload packet is the encapsulator of the packet (i.e., the other end
|
||||||
|
of the tunnel), looping can occur. In this case, the packet MUST be
|
||||||
|
discarded.
|
||||||
|
|
||||||
|
4. IPv4 as a Delivery Protocol
|
||||||
|
|
||||||
|
The IPv4 protocol 47 [RFC1700] is used when GRE packets are
|
||||||
|
enapsulated in IPv4. See [RFC1122] for requirements relating to the
|
||||||
|
delivery of packets over IPv4 networks.
|
||||||
|
|
||||||
|
5. Interoperation with RFC 1701 Compliant Implementations
|
||||||
|
|
||||||
|
In RFC 1701, the field described here as Reserved0 contained a number
|
||||||
|
of flag bits which this specification deprecates. In particular, the
|
||||||
|
Routing Present, Key Present, Sequence Number Present, and Strict
|
||||||
|
Source Route bits have been deprecated, along with the Recursion
|
||||||
|
Control field. As a result, the GRE header will never contain the
|
||||||
|
Key, Sequence Number or Routing fields specified in RFC 1701.
|
||||||
|
|
||||||
|
There are, however, existing implementations of RFC 1701. The
|
||||||
|
following sections describe correct interoperation with such
|
||||||
|
implementations.
|
||||||
|
|
||||||
|
5.1. RFC 1701 Compliant Receiver
|
||||||
|
|
||||||
|
An implementation complying to this specification will transmit the
|
||||||
|
Reserved0 field set to zero. An RFC 1701 compliant receiver will
|
||||||
|
interpret this as having the Routing Present, Key Present, Sequence
|
||||||
|
Number Present, and Strict Source Route bits set to zero, and will
|
||||||
|
not expect the RFC 1701 Key, Sequence Number or Routing fields to be
|
||||||
|
present.
|
||||||
|
|
||||||
|
5.2. RFC 1701 Compliant Transmitter
|
||||||
|
|
||||||
|
An RFC 1701 transmitter may set any of the Routing Present, Key
|
||||||
|
Present, Sequence Number Present, and Strict Source Route bits set to
|
||||||
|
one, and thus may transmit the RFC 1701 Key, Sequence Number or
|
||||||
|
Routing fields in the GRE header. As stated in Section 5.3, a packet
|
||||||
|
with non-zero bits in any of bits 1-5 MUST be discarded unless the
|
||||||
|
receiver implements RFC 1701.
|
||||||

||||||

|
||||||
|
6. Security Considerations
|
||||||
|
|
||||||
|
Security in a network using GRE should be relatively similar to
|
||||||
|
security in a normal IPv4 network, as routing using GRE follows the
|
||||||
|
same routing that IPv4 uses natively. Route filtering will remain
|
||||||
|
unchanged. However packet filtering requires either that a firewall
|
||||||
|
look inside the GRE packet or that the filtering is done on the GRE
|
||||||
|
tunnel endpoints. In those environments in which this is considered
|
||||||
|
to be a security issue it may be desirable to terminate the tunnel at
|
||||||
|
the firewall.
|
||||||
|
|
||||||
|
7. IANA Considerations
|
||||||
|
|
||||||
|
This section considers the assignment of additional GRE Version
|
||||||
|
Numbers and Protocol Types.
|
||||||
|
|
||||||
|
7.1. GRE Version Numbers
|
||||||
|
|
||||||
|
This document specifies GRE version number 0. GRE version number 1 is
|
||||||
|
used by PPTP [RFC2637]. Additional GRE version numbers are assigned
|
||||||
|
by IETF Consensus as defined in RFC 2434 [RFC2434].
|
||||||
|
|
||||||
|
7.2. Protocol Types
|
||||||
|
|
||||||
|
GRE uses an ETHER Type for the Protocol Type. New ETHER TYPES are
|
||||||
|
assigned by Xerox Systems Institute [RFC1700].

9. Appendix -- Known Issues
|
||||||
|
|
||||||
|
This document specifies the behavior of currently deployed GRE
|
||||||
|
implementations. As such, it does not attempt to address the

following known issues:
|
||||||
|
|
||||||
|
o Interaction Path MTU Discovery (PMTU) [RFC1191]
|
||||||
|
|
||||||
|
Existing implementations of GRE, when using IPv4 as the Delivery
|
||||||
|
Header, do not implement Path MTU discovery and do not set the
|
||||||
|
Don't Fragment bit in the Delivery Header. This can cause large
|
||||||
|
packets to become fragmented within the tunnel and reassembled at
|
||||||
|
the tunnel exit (independent of whether the payload packet is using
|
||||||
|
PMTU). If a tunnel entry point were to use Path MTU discovery,
|
||||||
|
however, that tunnel entry point would also need to relay ICMP
|
||||||
|
unreachable error messages (in particular the "fragmentation needed
|
||||||
|
and DF set" code) back to the originator of the packet, which is
|
||||||
|
not a requirement in this specification. Failure to properly relay
|
||||||
|
Path MTU information to an originator can result in the following
|
||||||
|
behavior: the originator sets the don't fragment bit, the packet
|
||||||
|
gets dropped within the tunnel, but since the originator doesn't
|
||||||
|
receive proper feedback, it retransmits with the same PMTU, causing
|
||||||
|
subsequently transmitted packets to be dropped.
|
||||||
|
|
||||||
|
o IPv6 as Delivery and/or Payload Protocol
|
||||||
|
|
||||||
|
This specification describes the intersection of GRE currently
|
||||||
|
deployed by multiple vendors. IPv6 as delivery and/or payload
|
||||||
|
protocol is not included in the currently deployed versions of GRE.
|
||||||
|

Abstract
|
||||||
|
|
||||||
|
Various routing protocols, including Open Shortest Path First (OSPF)
|
||||||
|
and Intermediate System to Intermediate System (ISIS), explicitly
|
||||||
|
allow "Equal-Cost Multipath" (ECMP) routing. Some router
|
||||||
|
implementations also allow equal-cost multipath usage with RIP and
|
||||||
|
other routing protocols. The effect of multipath routing on a
|
||||||
|
forwarder is that the forwarder potentially has several next-hops for
|
||||||
|
any given destination and must use some method to choose which next-
|
||||||
|
hop should be used for a given data packet.

1. Introduction
|
||||||
|
|
||||||
|
Various routing protocols, including OSPF and ISIS, explicitly allow
|
||||||
|
"Equal-Cost Multipath" routing. Some router implementations also
|
||||||
|
allow equal-cost multipath usage with RIP and other routing
|
||||||
|
protocols. Using equal-cost multipath means that if multiple equal-
|
||||||
|
cost routes to the same destination exist, they can be discovered and
|
||||||
|
used to provide load balancing among redundant paths.
|
||||||
|
|
||||||
|
The effect of multipath routing on a forwarder is that the forwarder
|
||||||
|
potentially has several next-hops for any given destination and must
|
||||||
|
use some method to choose which next-hop should be used for a given
|
||||||
|
data packet. This memo summarizes current practices, problems, and
|
||||||
|
solutions.

2. Concerns
|
||||||
|
|
||||||
|
Several router implementations allow multipath forwarding. This is
|
||||||
|
sometimes done naively via round-robin, where each packet matching a
|
||||||
|
given destination route is forwarded using the subsequent next-hop,
|
||||||
|
in a round-robin fashion. This does provide a form of load
|
||||||
|
balancing, but there are several problems with approaches such as
|
||||||
|
round-robin or random:
|
||||||
|
|
||||||
|
Variable Path MTU
|
||||||
|
Since each of the redundant paths may have a different MTU,
|
||||||
|
this means that the overall path MTU can change on a packet-
|
||||||
|
by-packet basis, negating the usefulness of path MTU discovery.
|
||||||
|
|
||||||
|
Variable Latencies
|
||||||
|
Since each of the redundant paths may have a different latency
|
||||||
|
involved, having packets take separate paths can cause packets
|
||||||
|
to always arrive out of order, increasing delivery latency and
|
||||||
|
buffering requirements.
|
||||||
|
|
||||||
|
Packet reordering causes TCP to believe that loss has taken
|
||||||
|
place when packets with higher sequence numbers arrive before
|
||||||
|
an earlier one. When three or more packets are received before
|
||||||
|
a "late" packet, TCP enters a mode called "fast-retransmit" [6]
|
||||||
|
which consumes extra bandwidth (which could potentially cause
|
||||||
|
more loss, decreasing throughput) as it attempts to
|
||||||
|
unnecessarily retransmit the delayed packet(s). Hence,
|
||||||
|
reordering can be detrimental to network performance.
|
||||||
|
|
||||||
|
Debugging
|
||||||
|
Common debugging utilities such as ping and traceroute are much
|
||||||
|
less reliable in the presence of multiple paths and may even
|
||||||
|
present completely wrong results.
|
||||||
|
|
||||||
|
In multicast routing, the problem with multiple paths is that
|
||||||
|
multicast routing protocols prevent loops and duplicates by
|
||||||
|
constructing a single tree to all receivers of the same group
|
||||||
|
address. Multicast routing protocols deployed today (DVMRP, PIM-DM,
|
||||||
|
PIM-SM) [2] construct shortest-path trees rooted at either the
|
||||||
|
source, or another router known as a Core or Rendezvous Point.
|
||||||
|
Hence, the way they ensure that duplicates will not arise is that a
|
||||||
|
given tree must use only a single next-hop towards the root of the
|
||||||
|
tree.

3. Requirements
|
||||||
|
|
||||||
|
In the remainder of this document, we will use the term "flow" to
|
||||||
|
represent the granularity at which the router keeps state (if at all)
|
||||||
|
for classes of traffic. The exact definition of a flow may depend on
|
||||||
|
the actual implementation. For example, a flow might be identified
|
||||||
|
solely by destination address, or it might be identified by (source
|
||||||
|
address, destination address, protocol id) triplet. Hence "flow" is
|
||||||
|
not necessarily synonymous with the term "microflow" as used in RFC
|
||||||
|
2474 [7], which also includes port numbers. Indeed, including
|
||||||
|
transport-layer information in the next-hop selection process can
|
||||||
|
actually be problematic. For example, if packets are fragmented, the
|
||||||
|
transport-layer information may not be available in every packet.
|
||||||
|
Furthermore, having the choice of path depend on transport-layer
|
||||||
|
fields may negate the benefit of caching information such as MTU for
|
||||||
|
use in subsequent connections between the same endpoints.
|
||||||
|
|
||||||
|
All of the problems outlined in the previous section arise when
|
||||||
|
packets in the same unicast or multicast "flow" are split among
|
||||||
|
multiple paths. The natural solution is therefore to ensure that
|
||||||
|
packets for the same flow always use the same path.
|
||||||
|
|
||||||
|
Two additional features are desirable:
|
||||||
|
|
||||||
|
Minimal disruption
|
||||||
|
When multipath is used, meaning that multiple routes contribute
|
||||||
|
valid next-hops, the chances are higher of routes being added
|
||||||
|
and deleted from consideration than when only the "best" route
|
||||||
|
is used (in which case metric changes in alternate routes have
|
||||||
|
no effect on traffic paths). Since a higher number of routes
|
||||||
|
may actually be used for forwarding when multipath is in use,
|
||||||
|
the potential for packet reordering and packet loss due to
|
||||||
|
route flaps can be much greater than when not using multipath.
|
||||||
|
Hence, it is desirable to minimize the number of active flows
|
||||||
|
affected by the addition or deletion of another next-hop.
|
||||||
|
|
||||||
|
Fast implementation
|
||||||
|
The amount of additional computation required to forward a
|
||||||
|
packet should be small. For example, when doing round-robin,
|
||||||
|
this computation might consist of incrementing (modulo the
|
||||||
|
number of next-hops) a next-hop index.
|
||||||
|
|
||||||
|
4. Solutions
|
||||||
|
|
||||||
|
We now provide three possible methods for improving the performance
|
||||||
|
of multipath and then discuss their applicability to unicast and
|
||||||
|
multicast forwarding.

RFC 2991 Multipath Issues November 2000
|
||||||
|
|
||||||
|
|
||||||
|
Modulo-N Hash
|
||||||
|
To select a next-hop from the list of N next-hops, the router
|
||||||
|
performs a modulo-N hash over the packet header fields that
|
||||||
|
identify a flow. This has the advantage of being fast, at the
|
||||||
|
expense of (N-1)/N of all flows changing paths whenever a
|
||||||
|
next-hop is added or removed.
|
||||||
|
|
||||||
|
Hash-Threshold
|
||||||
|
The router first selects a key by performing a hash over the
|
||||||
|
packet header fields that identify the flow. The N next-hops
|
||||||
|
have been assigned unique regions in the hash function's output
|
||||||
|
space. By comparing the hash value against region boundaries
|
||||||
|
the router can determine which region the hash value belongs to
|
||||||
|
and thus which next-hop to use. This method has the advantage
|
||||||
|
of only affecting flows near the region boundaries (or
|
||||||
|
thresholds) when next-hops are added or removed. For ECMP
|
||||||
|
hash-threshold's lookup can be done with a simple division
|
||||||
|
(hash_value / fixed_region_size). When a next-hop is added or
|
||||||
|
removed, between 1/4 and 1/2 of all flows change paths. An
|
||||||
|
analysis of this method can be found in [3].
|
||||||
|
|
||||||
|
Highest Random Weight (HRW)
|
||||||
|
The router computes a key for EACH next-hop by performing a
|
||||||
|
hash over the packet header fields that identify the flow, as
|
||||||
|
well as over the address of the next-hop. The router then
|
||||||
|
chooses the next-hop with the highest resulting key value [4].
|
||||||
|
This has the advantage of minimizing the number of flows
|
||||||
|
affected by a next-hop addition or deletion (only 1/N of them),
|
||||||
|
but is approximately N times as expensive as a modulo-N hash.
|
||||||
|
|
||||||
|
The applicability of these three alternatives depends on (at least)
|
||||||
|
two factors: whether the forwarder maintains per-flow state, and how
|
||||||
|
precious CPU is to a multipath forwarder.
|
||||||
|
|
||||||
|
Some routers may maintain per-flow state for reasons other than for
|
||||||
|
supporting multipath. For example, routers typically keep per-flow
|
||||||
|
state for multicast flows so that they can maintain the list of
|
||||||
|
interfaces to which packets in the flow should be copied.
|
||||||
|
|
||||||
|
If per-flow state is maintained in a multipath forwarder, then
|
||||||
|
computation of the next-hop can be done by the router at state
|
||||||
|
creation time. This entails no additional computations at packet
|
||||||
|
forwarding time compared with normal forwarding to a single next-hop,
|
||||||
|
since the next-hop is precomputed. In this case, any method can be
|
||||||
|
used, including round-robin, random, modulo-N, hash-threshold or HRW.
|
||||||
|
Hash functions such as modulo-N, hash-threshold and HRW are better if
|
||||||
|
the forwarder state may be deleted for any reason during the lifetime
|
||||||
|
of a flow since subsequent next-hop computations by the router will

||||||
|
|
||||||
|
|
||||||
|
always select the same path. This also improves the usefulness of
|
||||||
|
debugging utilities such as traceroute. Finally, to maximize the
|
||||||
|
stability of paths (and hence the usefulness of traceroute, etc.),
|
||||||
|
the use of HRW is recommended over the other methods mentioned
|
||||||
|
herein.
|
||||||
|
|
||||||
|
If per-flow state is not maintained by the forwarder, then using
|
||||||
|
multiple next-hops requires that the next-hop be calculated at packet
|
||||||
|
arrival time. When CPU is more precious than stability of flow
|
||||||
|
paths, hash-threshold is recommended over the other methods mentioned
|
||||||
|
herein.
|
||||||
|
|
||||||
|
4.1. Unicast Forwarding
|
||||||
|
|
||||||
|
Depending on the implementation, unicast forwarding may or may not
|
||||||
|
keep per-flow state. We recommend that where forwarder
|
||||||
|
implementations keep flow state, routers should use HRW at state
|
||||||
|
creation time (and next-hop deletion time) to select the next-hop,
|
||||||
|
and that forwarders without per-flow state use hash-threshold.
|
||||||
|
|
||||||
|
4.2. Multicast Forwarding
|
||||||
|
|
||||||
|
Today's multicast forwarding engines use a cache of forwarding
|
||||||
|
entries indexed by group (or group prefix) and source (or source
|
||||||
|
prefix). This means that today's multicast forwarder's always keep
|
||||||
|
per-flow state, although for some multicast routing protocols, the
|
||||||
|
"flow" may be fairly coarse (e.g., traffic from all sources to the
|
||||||
|
same destination). Since per-flow state is kept by the forwarder, it
|
||||||
|
is recommended that the router always use HRW to select the next-hop.
|
||||||
|
|
||||||
|
Routers using explicit-joining protocols such as PIM-SM [5] should
|
||||||
|
thus use the multipath information when determining to which neighbor
|
||||||
|
a join message should be sent. For example, when multiple next-hops
|
||||||
|
exist for a given Rendezvous Point (RP) toward which a (*,G) Join
|
||||||
|
should be sent, it is recommended that HRW be used to select the
|
||||||
|
next-hop to use for each group.
|
||||||
|
|
||||||
|
5. Applicability
|
||||||
|
|
||||||
|
The algorithms discussed above (except round-robin) all rely on some
|
||||||
|
form of hash function. Equal flow distribution is achieved when the
|
||||||
|
hash function is uniformly distributed. Since the commonly used hash
|
||||||
|
functions only become uniformly distributed when the number of inputs
|
||||||
|
is relatively large, these algorithms are more applicable to routers
|
||||||
|
used to route many flows, than in, for example, a small business
|
||||||
|
setting.

||||||

6. Redundant Parallel Links
|
||||||
|
|
||||||
|
A related problem occurs when multiple parallel links are used
|
||||||
|
between the same pair of routers. A common solution is to bundle the
|
||||||
|
two links together into a "super"-link when is then used for routing.
|
||||||
|
For multicast forwarding, this results in the two links being reduced
|
||||||
|
to a single next-hop (over the combined link) which can be used to
|
||||||
|
prevent duplicates. When a unicast or multicast packet is queued to
|
||||||
|
the combined link, some method, such as those discussed earlier, is
|
||||||
|
still required to determine the physical link on which to transmit
|
||||||
|
the packet. If the parallel links are identical, then most of the
|
||||||
|
concerns discussed in this document are avoided with the combined
|
||||||
|
link. The exception is packet reordering, which can still occur with
|
||||||
|
round-robin, adversely affecting TCP.
|
||||||
|
|
||||||
|
7. Security Considerations
|
||||||
|
|
||||||
|
This document discusses issues with various methods of choosing a
|
||||||
|
next-hop from among multiple valid next-hops. As such, it does not
|
||||||
|
directly impact the security of the Internet infrastructure or its
|
||||||
|
applications.
|
||||||
|
|
||||||
|
One issue that is worth mentioning, however, is that when next-hop
|
||||||
|
selection is predictable, an attacker can synthesize traffic that
|
||||||
|
will all hash the same, making it possible to launch a denial-of-
|
||||||
|
service attack that overloads a particular path. Since a special
|
||||||
|
case of this is when the same (single) next-hop is always selected,
|
||||||
|
such an attack is easiest when multipath is not being used.
|
||||||
|
Introducing multipath routing can make such an attack more difficult;
|
||||||
|
the more unpredictable the hash is, the harder it becomes to conduct
|
||||||
|
a denial-of-service attack against any single link.

1. Introduction
|
||||||
|
|
||||||
|
The IPv6 flow label has been redefined [RFC6437] and is now a
|
||||||
|
recommended IPv6 node requirement [RFC6434]. Its use for load
|
||||||
|
sharing in multipath routing has been specified [RFC6438]. Another
|
||||||
|
scenario in which the flow label could be used is in load
|
||||||
|
distribution for large server farms. Load distribution is a slightly
|
||||||
|
more general term than load balancing, but the latter is more
|
||||||
|
commonly used. In the context of a server farm, both terms refer to
|
||||||
|
mechanisms that distribute the workload of a server farm among
|
||||||
|
different servers in order to optimize performance. Server load
|
||||||
|
balancing commonly applies to HTTP traffic, but most of the
|
||||||
|
techniques described would apply to other upper-layer applications as
|
||||||
|
well. This document starts with brief introductions to the flow
|
||||||
|
label and to server load-balancing techniques, and then describes how
|
||||||
|
the flow label can be used to enhance load balancers operating on IP
|
||||||
|
packets and TCP sessions, commonly known as layer 3/4 load balancers.
|
||||||
|
|
||||||
|
The motivation for this approach is to improve the performance of
|
||||||
|
most types of layer 3/4 load balancers, especially for traffic
|
||||||
|
including multiple IPv6 extension headers and in particular for
|
||||||
|
fragmented packets. Fragmented packets, often the result of
|
||||||
|
customers reaching the load balancer via a VPN with a limited MTU,
|
||||||
|
are a common performance problem.
|
||||||
|
|
||||||
|
2. Summary of Flow Label Specification
|
||||||
|
|
||||||
|
The IPv6 flow label [RFC6437] is a 20-bit field included in every
|
||||||
|
IPv6 header [RFC2460]. It is recommended to be supported in all IPv6
|
||||||
|
nodes by [RFC6434]. There is additional background material in
|
||||||
|
[RFC6436] and [RFC6294]. According to its definition, the flow label
|
||||||
|
should be set to a constant value for a given traffic flow (such as
|
||||||
|
an HTTP connection), and that value will belong to a uniform
|
||||||
|
statistical distribution, making it potentially valuable for load-
|
||||||
|
balancing purposes.

RFC 7098 Flow Label for Server Load Balancing January 2014
|
||||||
|
|
||||||
|
|
||||||
|
Any device that has access to the IPv6 header has access to the flow
|
||||||
|
label, and it is at a fixed position in every IPv6 packet. In
|
||||||
|
contrast, transport-layer information, such as the port numbers, is
|
||||||
|
not always in a fixed position, since it follows any IPv6 extension
|
||||||
|
headers that may be present. In fact, the logic of finding the
|
||||||
|
transport header is always more complex for IPv6 than for IPv4, due
|
||||||
|
to the absence of an Internet Header Length field in IPv6.
|
||||||
|
Additionally, if packets are fragmented, the flow label will be
|
||||||
|
present in all fragments, but the transport header will only be in
|
||||||
|
one packet. Therefore, within the lifetime of a given transport-
|
||||||
|
layer connection, the flow label can be a more convenient "handle"
|
||||||
|
than the port number for identifying that particular connection.
|
||||||
|
|
||||||
|
According to RFC 6437, source hosts should set the flow label;
|
||||||
|
however, if they do not (i.e., its value is zero), forwarding nodes
|
||||||
|
(such as the first-hop router) may set it instead. In both cases,
|
||||||
|
the flow label value must be constant for a given transport session,
|
||||||
|
normally identified by the IPv6 and Transport header 5-tuple. By
|
||||||
|
default, the flow label value should be calculated by a stateless
|
||||||
|
algorithm. The resulting value should form part of a statistically
|
||||||
|
uniform distribution, regardless of which node sets it.
|
||||||
|
|
||||||
|
It is recognized that at the time of writing, very few traffic flows
|
||||||
|
include a non-zero flow label value. The mechanism described below
|
||||||
|
is one that can be added to existing load-balancing mechanisms, so
|
||||||
|
that it will become effective as more and more flows contain a non-
|
||||||
|
zero label. Even if the flow label is chosen from an imperfectly
|
||||||
|
uniform distribution, it will nevertheless increase the information
|
||||||
|
entropy of the IPv6 header as a whole. This allows for progressive
|
||||||
|
introduction of load balancing based on the flow label.
|
||||||
|
|
||||||
|
If the recommendations in Section 3 of RFC 6437 are followed for
|
||||||
|
traffic from a given source accessing a well-known TCP port at a
|
||||||
|
given destination, the flow label can act as a substitute for the
|
||||||
|
port numbers as far as a load balancer is concerned, and it can be
|
||||||
|
found at a fixed position in the layer 3 header even if extension
|
||||||
|
headers are present.
|
||||||
|
|
||||||
|
The flow label is defined as an end-to-end component of the IPv6
|
||||||
|
header, but there are three qualifications to this:
|
||||||
|
|
||||||
|
1. Until the IPv6 flow label specification in RFC 6437 is widely
|
||||||
|
implemented as recommended by RFC 6434, the flow label will often
|
||||||
|
be set to the default value of zero.

||||||

||||||

||||||

|
||||||
|
|
||||||
|
|
||||||
|
2. Because of the recommendation to use a stateless algorithm to
|
||||||
|
calculate the label, there is a low (but non-zero) probability
|
||||||
|
that two simultaneous flows from the same source to the same
|
||||||
|
destination have the same flow label value despite having
|
||||||
|
different transport-protocol port numbers.
|
||||||
|
|
||||||
|
3. The Flow Label field is in an unprotected part of the IPv6
|
||||||
|
header, which means that intentional or unintentional changes to
|
||||||
|
its value cannot be easily detected by a receiver.
|
||||||
|
|
||||||
|
The first two points are addressed below in Section 4 and the third
|
||||||
|
in Section 5.

||||||

||||||
|
3. Summary of Server Farm Load-Balancing Techniques
|
||||||
|
|
||||||
|
Load balancing for server farms is achieved by a variety of methods,
|
||||||
|
often used in combination [Tarreau]. This section gives a general
|
||||||
|
overview of common methods, although the flow label is not relevant
|
||||||
|
to all of them. The actual load-balancing algorithm (the choice of
|
||||||
|
which server to use for a new client session) is irrelevant to this
|
||||||
|
discussion. We give examples for HTTP, but analogous techniques may
|
||||||
|
be used for other application protocols.
|
||||||
|
|
||||||
|
o The simplest method is using the DNS to return different server
|
||||||
|
addresses for a single name such as www.example.com to different
|
||||||
|
users. This is typically done by rotating the order in which
|
||||||
|
different addresses within the server site are listed by the
|
||||||
|
relevant authoritative DNS server, on the assumption that the
|
||||||
|
client will pick the first one. Routing may be configured such
|
||||||
|
that the different addresses are handled by different ingress
|
||||||
|
routers. Several variants of this load-balancing mechanism exist,
|
||||||
|
such as expecting some clients to use all the advertised addresses
|
||||||
|
when multiple connections are involved, or directing the traffic
|
||||||
|
to multiple sites, also known as global load balancing. None of
|
||||||
|
these mechanisms are in the scope of this document, and the
|
||||||
|
proposal in this document does not affect their usability nor aim
|
||||||
|
to replace them, so they will not be discussed further.
|
||||||
|
|
||||||
|
o Another method, for HTTP servers, is to operate a layer 7 reverse
|
||||||
|
proxy in front of the server farm. The reverse proxy will present
|
||||||
|
a single IP address to the world, communicated to clients by a
|
||||||
|
single AAAA record. For each new client session (an incoming TCP
|
||||||
|
connection and HTTP request), it will pick a particular server and
|
||||||
|
proxy the session to it. The act of proxying should be more
|
||||||
|
efficient and less resource-intensive than the act of serving the
|
||||||
|
required content. The proxy must retain TCP state and proxy state
|
||||||
|
for the duration of the session. This TCP state could,
|
||||||
|
potentially, include the incoming flow label value.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Carpenter, et al. Informational [Page 4]
|
||||||
|
|
||||||
|
RFC 7098 Flow Label for Server Load Balancing January 2014
|
||||||
|
|
||||||
|
|
||||||
|
o A component of some load-balancing systems is an SSL reverse proxy
|
||||||
|
farm. The individual SSL proxies handle all cryptographic aspects
|
||||||
|
and exchange unencrypted HTTP with the actual servers. Thus, from
|
||||||
|
the load-balancing point of view, this really looks just like a
|
||||||
|
server farm, except that it's specialized for HTTPS. Each proxy
|
||||||
|
will retain SSL and TCP and maybe HTTP state for the duration of
|
||||||
|
the session, and the TCP state could potentially include the flow
|
||||||
|
label.
|
||||||
|
|
||||||
|
o Finally the "front end" of many load-balancing systems is a layer
|
||||||
|
3/4 load balancer. While it can be a dedicated device, it is also
|
||||||
|
a standard function of some network switches or routers (e.g.
|
||||||
|
using Equal-Cost Multipath Routing (ECMP) [RFC2991]). In this
|
||||||
|
case, it is the layer 3/4 load balancer whose IP address is
|
||||||
|
published as the primary AAAA record for the service. All client
|
||||||
|
sessions will pass through this device. Depending on the specific
|
||||||
|
scenario, the balancer will assign new sessions among the actual
|
||||||
|
application servers, across an SSL proxy farm, or among a set of
|
||||||
|
layer 7 proxies. In all cases, the layer 3/4 load balancer has to
|
||||||
|
classify incoming packets very quickly and choose the target
|
||||||
|
server or proxy so as to ensure persistence. 'Persistence' is
|
||||||
|
defined as the guarantee that a given client session will run to
|
||||||
|
completion on a single server. The layer 3/4 load balancer
|
||||||
|
therefore needs to inspect each incoming packet to classify it.
|
||||||
|
There are two common types of layer 3/4 load balancers, the
|
||||||
|
totally stateless ones which only act on single packets, generally
|
||||||
|
involving a per-packet hashing of easy-to-find information such as
|
||||||
|
the source address and/or port into a server number, and the
|
||||||
|
stateful ones that take the routing decision on the very first
|
||||||
|
packets of a session and maintain the same direction for all
|
||||||
|
packets belonging to the same session. Clearly, both types of
|
||||||
|
layer 3/4 balancers could inspect and make use of the flow label
|
||||||
|
value.
|
||||||
|
|
||||||
|
Our focus is on how the balancer identifies a particular flow.
|
||||||
|
For clarity, note that two aspects of layer 3/4 load balancers are
|
||||||
|
not affected by use of the flow label to identify sessions:
|
||||||
|
|
||||||
|
1. Balancers use various techniques to redirect traffic to a
|
||||||
|
specific target server.
|
||||||
|
|
||||||
|
+ All servers are configured with the same IP address, they
|
||||||
|
are all on the same LAN, and the load balancer sends
|
||||||
|
directly to their individual MAC addresses. In this case,
|
||||||
|
return packets from the server to the client are sent back
|
||||||
|
without passing through the balancer, a technique known as
|
||||||
|
direct server return, but we are not concerned here with
|
||||||
|
the return packets.
|
||||||
|
|
||||||
|

||||||

||||||

|
||||||
|
|
||||||
|
|
||||||
|
+ All servers are configured with the same IP address,
|
||||||
|
treated locally as an anycast address by layer 3 ECMP
|
||||||
|
routing.
|
||||||
|
|
||||||
|
+ Each server has its own IP address, and the balancer uses
|
||||||
|
an IP-in-IP tunnel to reach it.
|
||||||
|
|
||||||
|
+ Each server has its own IP address, and the balancer
|
||||||
|
performs NAPT (Network Address and Port Translation) to
|
||||||
|
deliver the client's packets to that address.
|
||||||
|
|
||||||
|
+ The choice between these methods is not affected by use of
|
||||||
|
the flow label.
|
||||||
|
|
||||||
|
2. A layer 3/4 balancer must correctly handle Path MTU Discovery
|
||||||
|
by forwarding relevant ICMPv6 packets in both directions.
|
||||||
|
This too is not directly affected by use of the flow label.
|
||||||
|
It should be noted that there may be difficulty correlating an
|
||||||
|
ICMPv6 "Packet too big" response with the session it refers
|
||||||
|
to, but that is out of the scope of the present document.
|
||||||
|
|
||||||
|
The following diagram, inspired by [Tarreau], shows a layout with
|
||||||
|
various methods in use together. (Below, "ASIC" stands for
|

From the previous paragraphs, we can identify several points in this
|
||||||
|
diagram where the flow label might be relevant:
|
||||||
|
|
||||||
|
1. Layer 3/4 load balancers.
|
||||||
|
|
||||||
|
2. SSL proxies.
|
||||||
|
|
||||||
|
3. HTTP proxies.
|
||||||
|
|
||||||
|
However, usage by the proxies seems unlikely to affect performance,
|
||||||
|
because they must in any case process the application-layer header,
|
||||||
|
so in this document we focus only on layer 3/4 balancers.

||||||
|
4. Applying the Flow Label to Layer 3/4 Load Balancing
|
||||||
|
|
||||||
|
The suggested model for using the flow label to enhance an layer 3/4
|
||||||
|
load-balancing mechanism is as follows:
|
||||||
|
|
||||||
|
o We are only concerned with IPv6 traffic in which the flow label
|
||||||
|
value has been set according to [RFC6437]. If the flow label of
|
||||||
|
an incoming packet is zero, load balancers will continue to use
|
||||||
|
the transport header in the traditional way. As the use of the
|
||||||
|
flow label becomes more prevalent according to RFC 6434, load
|
||||||
|
balancers, and therefore users, will reap a growing performance
|
||||||
|
benefit.
|
||||||
|
|
||||||
|
o If the flow label of an incoming packet is non-zero, layer 3/4
|
||||||
|
load balancers can use the 2-tuple {source address, flow label} as
|
||||||
|
the session key for whatever load distribution algorithm they
|
||||||
|
support. Alternatively, they might use the 3-tuple {dest address,
|
||||||
|
source address, flow label}, especially if the server farm
|
||||||
|
supports multiple server IP addresses, but using the 3-tuple will
|
||||||
|
be significantly quicker than searching for the transport port
|
||||||
|
numbers later in the packet. Moreover, the transport-layer
|
||||||
|
information such as the source port is not repeated in fragments,
|
||||||
|
which generally prevents stateless load balancers from supporting
|
||||||
|
fragmented traffic since they generally cannot reassemble
|
||||||
|
fragments.
|
||||||
|
|
||||||
|
A stateless layer 3/4 load balancer would simply apply a hash
|
||||||
|
algorithm to the 2-tuple or 3-tuple on all packets in order to
|
||||||
|
select the same target server consistently for a given flow.
|
||||||
|
Needless to say, the hash algorithm has to be well chosen for its
|
||||||
|
purpose, but this problem is common to several forms of stateless
|
||||||
|
load balancing. The discussion in [RFC6438] applies.
|
||||||
|
|
||||||
|
A stateful layer 3/4 load balancer would apply its usual load
|
||||||
|
distribution algorithm to the first packet of a session, and store
|
||||||
|
the {tuple, server} association in a table so that subsequent
|
||||||
|
packets belonging to the same session are forwarded to the same
|
||||||
|
server. Thus, for all subsequent packets of the session, it can
|
||||||
|
ignore all IPv6 extension headers, which should lead to a
|
||||||
|
performance benefit. Whether this benefit is valuable will depend
|
||||||
|
on engineering details of the specific load balancer.
|
||||||
|
|
||||||
|
Note that such a balancer will not identify new transport sessions
|
||||||
|
from the same source that use the same flow label; they will be
|
||||||
|
delivered to the same server. This is like the behavior of
|
||||||
|
existing hash-based layer 4 balancers that always send similarly
|
||||||
|
hashed packets to the same destination. However, a global state
|
||||||
|
table in a flow label balancer cannot be shared between multiple
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Carpenter, et al. Informational [Page 8]
|
||||||
|
|
||||||
|
RFC 7098 Flow Label for Server Load Balancing January 2014
|
||||||
|
|
||||||
|
|
||||||
|
services if these services rely on transport-layer information,
|
||||||
|
since the goal of using the flow label is to avoid looking up that
|
||||||
|
information.
|
||||||
|
|
||||||
|
A related issue is that the balancer will not detect FIN/ACK
|
||||||
|
sequences at the end of sessions. Therefore, it will rely on
|
||||||
|
inactivity timers to delete session state. However, all existing
|
||||||
|
balancers must maintain such timers to deal with hung sessions,
|
||||||
|
and the practical impact on memory utilization is unlikely to be
|
||||||
|
significant.
|
||||||
|
|
||||||
|
o Layer 3/4 balancers that redirect the incoming packets by NAPT are
|
||||||
|
not expected to obtain any saving of time by using the flow label,
|
||||||
|
because they have no choice but to follow the extension header
|
||||||
|
chain in order to locate and modify the port number and transport
|
||||||
|
checksum. The same would apply to balancers that perform TCP
|
||||||
|
state tracking for any reason.
|
||||||
|
|
||||||
|
o Note that correct handling of ICMPv6 for Path MTU Discovery
|
||||||
|
requires the layer 3/4 balancer to keep state for the client
|
||||||
|
source address, independently of either the port numbers or the
|
||||||
|
flow label.
|
||||||
|
|
||||||
|
o SSL and HTTP proxies, if present, should forward the flow label
|
||||||
|
value towards the server. This usually has no performance
|
||||||
|
benefit, but it is consistent with the general model for the flow
|
||||||
|
label described in RFC 6437.
|
||||||
|
|
||||||
|
It should be noted that the performance benefit, if any, depends
|
||||||
|
entirely on engineering trade-offs in the design of the layer 3/4
|
||||||
|
balancer. An extra test is needed to check if the label is non-zero,
|
||||||
|
but if there is a non-zero label, all logic for handling extension
|
||||||
|
headers can be skipped except for the first packet of a new flow.
|
||||||
|
Since the identifying state to be stored is only the tuple and the
|
||||||
|
server identifier, storage requirements will be reduced.
|
||||||
|
Additionally, the method will work for fragmented traffic and for
|
||||||
|
flows where the transport information is missing (unknown transport
|
||||||
|
protocol) or obfuscated (e.g., IPsec). Traffic reaching the load
|
||||||
|
balancer via a VPN is particularly prone to the fragmentation issue,
|
||||||
|
due to MTU size issues. For some load-balancer designs, these are
|
||||||
|
very significant advantages.
|
||||||
|
|
||||||
|
In the unlikely event of two simultaneous flows from the same source
|
||||||
|
address having the same flow label value, the two flows would end up
|
||||||
|
assigned to the same server, where they would be distinguished as
|
||||||
|
normal by their port numbers. There are approximately one million
|
||||||
|
possible flow label values, and if the rules for flow label
|
||||||
|
generation [RFC6437] are followed, this would be a statistically rare
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Carpenter, et al. Informational [Page 9]
|
||||||
|
|
||||||
|
RFC 7098 Flow Label for Server Load Balancing January 2014
|
||||||
|
|
||||||
|
|
||||||
|
event, and would not damage the overall load-balancing effect.
|
||||||
|
Moreover, with a million possible label values, it is very likely
|
||||||
|
that there will be many more flow label values than servers at most
|
||||||
|
sites, so it is already expected that multiple flow label values will
|
||||||
|
end up on the same server for a given client IP address.
|
||||||
|
|
||||||
|
In the case that many thousands of clients are hidden behind the same
|
||||||
|
large-scale NAPT with a single shared IP address, the assumption of
|
||||||
|
low probability of conflicts might become incorrect, unless flow
|
||||||
|
label values are random enough to avoid following similar sequences
|
||||||
|
for all clients. This is not expected to be a factor for IPv6
|
||||||
|
anyway, since there is no need to implement large-scale NAPT with
|
||||||
|
address sharing [RFC4864]. The probability of conflicts is low for
|
||||||
|
sites that implement network prefix translation [RFC6296], since this
|
||||||
|
technique provides a different address for each client.
|
||||||
|
|
||||||
|
5. Security Considerations
|
||||||
|
|
||||||
|
Security aspects of the flow label are discussed in [RFC6437]. As
|
||||||
|
noted there, a malicious source or man-in-the-middle could disturb
|
||||||
|
load balancing by manipulating flow labels. This risk already exists
|
||||||
|
today where the source address and port are used as a hashing key in
|
||||||
|
layer 3/4 load balancers, as well as where a persistence cookie is
|
||||||
|
used in HTTP to designate a server. It even exists on layer 3
|
||||||
|
components that only rely on the source address to select a
|
||||||
|
destination, making them more DDoS-prone. Nevertheless, all these
|
||||||
|
methods are currently used because the benefits for load balancing
|
||||||
|
and persistence hugely outweigh the risks. The flow label does not
|
||||||
|
significantly alter this situation.
|
||||||
|
|
||||||
|
Specifically, the IPv6 flow label specification [RFC6437] states that
|
||||||
|
"stateless classifiers should not use the flow label alone to control
|
||||||
|
load distribution, and stateful classifiers should include explicit
|
||||||
|
methods to detect and ignore suspect flow label values." The former
|
||||||
|
point is answered by also using the source address. The latter point
|
||||||
|
is more complex. If the risk is considered serious, the site ingress
|
||||||
|
router or the layer 3/4 balancer should use a suitable heuristic to
|
||||||
|
verify incoming flows with non-zero flow label values. If a flow
|
||||||
|
from a given source address and port number does not have a constant
|
||||||
|
flow label value, it is suspect and should be dropped. This would
|
||||||
|
deal with both intentional and accidental changes to the flow label.
|
||||||
|
|
||||||
|
A malicious source or man-in-the-middle could generate a flow in
|
||||||
|
which the flow label is constant but the transport port numbers in
|
||||||
|
some packets are invalid. Such packets, if load-balanced only on the
|
||||||
|
basis of the flow label, could reach the target server and create a
|
||||||
|
single-source DoS attack on its TCP engine.

channel risk is considered significant, a firewall might rewrite non-
|
||||||
|
zero flow labels. As long as this is done as described in RFC 6437,
|
||||||
|
it will not invalidate the mechanisms described above.
|
||||||
|
|
||||||
|
The flow label may be of use in protecting against DDoS attacks
|
||||||
|
against servers. As noted in RFC 6437, a source should generate flow
|
||||||
|
label values that are hard to predict, most likely by including a
|
||||||
|
secret nonce in the hash used to generate each label. The attacker
|
||||||
|
does not know the nonce and therefore has no way to invent flow
|
||||||
|
labels that will all target the same server, even with knowledge of
|
||||||
|
both the hash algorithm and the load-balancing algorithm. Still, it
|
||||||
|
is important to understand that it is always trivial to force a load
|
||||||
|
balancer to stick to the same server during an attack, so the
|
||||||
|
security of the whole solution must not rely on the unpredictability
|
||||||
|
of the flow label values alone, but should include defensive measures
|
||||||
|
like most load balancers already have against abnormal use of source
|
||||||
|
addresses or session cookies.
|
||||||
|
|
||||||
|
New flows are assigned to a server according to any of the usual
|
||||||
|
algorithms available on the load balancer (e.g., least connections,
|
||||||
|
round robin, etc.). The association between the 2-tuple {source
|
||||||
|
address, flow label} and the server is stored in a table (often
|
||||||
|
called stick table) so that future traffic from the same source using
|
||||||
|
the same flow label can be sent to the same server. This method is
|
||||||
|
more robust against a loss of server and also makes it harder for an
|
||||||
|
attacker to target a specific server, because the association between
|
||||||
|
a flow label value and a server is not known externally.
|
||||||
|
|
||||||
|
In the case that a stateless hash function is used to assign client
|
||||||
|
packets to specific servers, it may be advisable to use a
|
||||||
|
cryptographic hash function of some kind, to ensure that an attacker
|
||||||
|
cannot predict the behavior of the load balancer.

User Datagram Protocol
|
||||||
|
----------------------
|
||||||
|
|
||||||
|
Introduction
|
||||||
|
------------
|
||||||
|
|
||||||
|
This User Datagram Protocol (UDP) is defined to make available a
|
||||||
|
datagram mode of packet-switched computer communication in the
|
||||||
|
environment of an interconnected set of computer networks. This
|
||||||
|
protocol assumes that the Internet Protocol (IP) [1] is used as the
|
||||||
|
underlying protocol.
|
||||||
|
|
||||||
|
This protocol provides a procedure for application programs to send
|
||||||
|
messages to other programs with a minimum of protocol mechanism. The
|
||||||
|
protocol is transaction oriented, and delivery and duplicate protection
|
||||||
|
are not guaranteed. Applications requiring ordered reliable delivery of
|
||||||
|
streams of data should use the Transmission Control Protocol (TCP) [2].

||||||

|

|
Fields
|
||||||
|
------
|
||||||
|
|
||||||
|
Source Port is an optional field, when meaningful, it indicates the port
|
||||||
|
of the sending process, and may be assumed to be the port to which a
|
||||||
|
reply should be addressed in the absence of any other information. If
|
||||||
|
not used, a value of zero is inserted.

User Datagram Protocol RFC 768
|
||||||
|
Fields
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Destination Port has a meaning within the context of a particular
|
||||||
|
internet destination address.
|
||||||
|
|
||||||
|
Length is the length in octets of this user datagram including this
|
||||||
|
header and the data. (This means the minimum value of the length is
|
||||||
|
eight.)
|
||||||
|
|
||||||
|
Checksum is the 16-bit one's complement of the one's complement sum of a
|
||||||
|
pseudo header of information from the IP header, the UDP header, and the
|
||||||
|
data, padded with zero octets at the end (if necessary) to make a
|
||||||
|
multiple of two octets.
|
||||||
|
|
||||||
|
The pseudo header conceptually prefixed to the UDP header contains the
|
||||||
|
source address, the destination address, the protocol, and the UDP
|
||||||
|
length. This information gives protection against misrouted datagrams.
|
||||||
|
This checksum procedure is the same as is used in TCP.
|
||||||
|
|
||||||
|
0 7 8 15 16 23 24 31
|
||||||
|
+--------+--------+--------+--------+
|
||||||
|
| source address |
|
||||||
|
+--------+--------+--------+--------+
|
||||||
|
| destination address |
|
||||||
|
+--------+--------+--------+--------+
|
||||||
|
| zero |protocol| UDP length |
|
||||||
|
+--------+--------+--------+--------+
|
||||||
|
|
||||||
|
If the computed checksum is zero, it is transmitted as all ones (the
|
||||||
|
equivalent in one's complement arithmetic). An all zero transmitted
|
||||||
|
checksum value means that the transmitter generated no checksum (for
|
||||||
|
debugging or for higher level protocols that don't care).
|
||||||
|
|
||||||
|
User Interface
|
||||||
|
--------------
|
||||||
|
|
||||||
|
A user interface should allow
|
||||||
|
|
||||||
|
the creation of new receive ports,
|
||||||
|
|
||||||
|
receive operations on the receive ports that return the data octets
|
||||||
|
and an indication of source port and source address,
|
||||||
|
|
||||||
|
and an operation that allows a datagram to be sent, specifying the
|
||||||
|
data, source and destination ports and addresses to be sent.
|
||||||

|
IP Interface
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
IP Interface
|
||||||
|
-------------
|
||||||
|
|
||||||
|
The UDP module must be able to determine the source and destination
|
||||||
|
internet addresses and the protocol field from the internet header. One
|
||||||
|
possible UDP/IP interface would return the whole internet datagram
|
||||||
|
including all of the internet header in response to a receive operation.
|
||||||
|
Such an interface would also allow the UDP to pass a full internet
|
||||||
|
datagram complete with header to the IP to send. The IP would verify
|
||||||
|
certain fields for consistency and compute the internet header checksum.
|
||||||
|
|
||||||
|
Protocol Application
|
||||||
|
--------------------
|
||||||
|
|
||||||
|
The major uses of this protocol is the Internet Name Server [3], and the
|
||||||
|
Trivial File Transfer [4].
|
||||||
|
|
||||||
|
Protocol Number
|
||||||
|
---------------
|
||||||
|
|
||||||
|
This is protocol 17 (21 octal) when used in the Internet Protocol.
|
||||||
|
Other protocol numbers are listed in [5].

A Standard for the Transmission of IP Datagrams over Ethernet Networks
|
||||||
|
|
||||||
|
|
||||||
|
Status of this Memo
|
||||||
|
|
||||||
|
This RFC specifies a standard method of encapsulating Internet
|
||||||
|
Protocol (IP) [1] datagrams on an Ethernet [2]. This RFC specifies a
|
||||||
|
standard protocol for the ARPA-Internet community.
|
||||||
|
|
||||||
|
Introduction
|
||||||
|
|
||||||
|
This memo applies to the Ethernet (10-megabit/second, 48-bit
|
||||||
|
addresses). The procedure for transmission of IP datagrams on the
|
||||||
|
Experimental Ethernet (3-megabit/second, 8-bit addresses) is
|
||||||
|
described in [3].
|
||||||
|
|
||||||
|
Frame Format
|
||||||
|
|
||||||
|
IP datagrams are transmitted in standard Ethernet frames. The type
|
||||||
|
field of the Ethernet frame must contain the value hexadecimal 0800.
|
||||||
|
The data field contains the IP header followed immediately by the IP
|
||||||
|
data.
|
||||||
|
|
||||||
|
The minimum length of the data field of a packet sent over an
|
||||||
|
Ethernet is 46 octets. If necessary, the data field should be padded
|
||||||
|
(with octets of zero) to meet the Ethernet minimum frame size. This
|
||||||
|
padding is not part of the IP packet and is not included in the total
|
||||||
|
length field of the IP header.
|
||||||
|
|
||||||
|
The minimum length of the data field of a packet sent over an
|
||||||
|
Ethernet is 1500 octets, thus the maximum length of an IP datagram
|
||||||
|
sent over an Ethernet is 1500 octets. Implementations are encouraged
|
||||||
|
to support full-length packets. Gateway implementations MUST be
|
||||||
|
prepared to accept full-length packets and fragment them if
|
||||||
|
necessary. If a system cannot receive full-length packets, it should
|
||||||
|
take steps to discourage others from sending them, such as using the
|
||||||
|
TCP Maximum Segment Size option [4].
|
||||||
|
|
||||||
|
Note: Datagrams on the Ethernet may be longer than the general
|
||||||
|
Internet default maximum packet size of 576 octets. Hosts connected
|
||||||
|
to an Ethernet should keep this in mind when sending datagrams to
|
||||||
|
hosts not on the same Ethernet. It may be appropriate to send
|
||||||
|
smaller datagrams to avoid unnecessary fragmentation at intermediate
|
||||||
|
gateways. Please see [4] for further information on this point.

Address Mappings
|
||||||
|
|
||||||
|
The mapping of 32-bit Internet addresses to 48-bit Ethernet addresses
|
||||||
|
can be done several ways. A static table could be used, or a dynamic
|
||||||
|
discovery procedure could be used.
|
||||||
|
|
||||||
|
Static Table
|
||||||
|
|
||||||
|
Each host could be provided with a table of all other hosts on the
|
||||||
|
local network with both their Ethernet and Internet addresses.
|
||||||
|
|
||||||
|
Dynamic Discovery
|
||||||
|
|
||||||
|
Mappings between 32-bit Internet addresses and 48-bit Ethernet
|
||||||
|
addresses could be accomplished through the Address Resolution
|
||||||
|
Protocol (ARP) [5]. Internet addresses are assigned arbitrarily
|
||||||
|
on some Internet network. Each host's implementation must know
|
||||||
|
its own Internet address and respond to Ethernet Address
|
||||||
|
Resolution packets appropriately. It should also use ARP to
|
||||||
|
translate Internet addresses to Ethernet addresses when needed.
|
||||||
|
|
||||||
|
Broadcast Address
|
||||||
|
|
||||||
|
The broadcast Internet address (the address on that network with a
|
||||||
|
host part of all binary ones) should be mapped to the broadcast
|
||||||
|
Ethernet address (of all binary ones, FF-FF-FF-FF-FF-FF hex).
|
||||||
|
|
||||||
|
The use of the ARP dynamic discovery procedure is strongly
|
||||||
|
recommended.
|
||||||
|
|
||||||
|
Trailer Formats
|
||||||
|
|
||||||
|
Some versions of Unix 4.2bsd use a different encapsulation method in
|
||||||
|
order to get better network performance with the VAX virtual memory
|
||||||
|
architecture. Consenting systems on the same Ethernet may use this
|
||||||
|
format between themselves.
|
||||||
|
|
||||||
|
No host is required to implement it, and no datagrams in this format
|
||||||
|
should be sent to any host unless the sender has positive knowledge
|
||||||
|
that the recipient will be able to interpret them. Details of the
|
||||||
|
trailer encapsulation may be found in [6].
|
||||||
|
|
||||||
|
(Note: At the present time Unix 4.2bsd will either always use
|
||||||
|
trailers or never use them (per interface), depending on a boot-time
|
||||||
|
option. This is expected to be changed in the future. Unix 4.2bsd
|
||||||
|
also uses a non-standard Internet broadcast address with a host part
|
||||||
|
of all zeroes, this may also be changed in the future.)
