Title : Protocol Extensions for Header Compression over MPLS
Author(s) : J. Ash, et al.
Filename : draft-ietf-avt-hc-over-mpls-protocol-08.txt
Pages : 32
Date : 2007-2-16
This specification defines how to use Multi-Protocol Label Switching
(MPLS) to route Header-Compressed (HC) packets over an MPLS label
switched path. HC can significantly reduce packet-header overhead
and, in combination with MPLS, can also increases bandwidth
efficiency and processing scalability in terms of the maximum number
of simultaneous compressed flows that use HC at each router). Here
we define how MPLS pseudowires are used to transport the HC context
and control messages between the ingress and egress MPLS label
switching routers. This is defined for a specific set of existing HC
mechanisms that might be used, for example, to support voice over IP.
This specification also describes extension mechanisms to allow
support for future, as yet to be defined, HC protocols. In this
specification, each HC protocol operates independently over a single
pseudowire instance very much as it would over a single
point-to-point link.

In the body type:
"FILE /internet-drafts/draft-ietf-avt-hc-over-mpls-protocol-08.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
