A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Site Multihoming by IPv6 Intermediation Working Group of the IETF.
Title : Level 3 multihoming shim protocol
Author(s) : E. Nordmark
Filename : draft-ietf-shim6-proto-01.txt
Pages : 52
Date : 2005-10-12
The SHIM6 working group is exploring a layer 3 shim approach for
providing locator agility below the transport protocols, so that
multihoming can be provided for IPv6 with failover and load spreading
properties, without assuming that a multihomed site will have a
provider independent IPv6 address which is announced in the global
IPv6 routing table. The hosts in a site which has multiple provider
allocated IPv6 address prefixes, will use the shim6 protocol
specified in this document to setup state with peer hosts, so that
the state can later be used to failover to a different locator pair,
should the original one stop working.
This document picks a particular approach to such a protocol and
tries to flush out a bunch of details, with the hope that the WG can
better understand the details in this proposal as well as discovering
and understanding alternative designs that might be better. Thus
this proposal is my no means cast in stone as the direction; quite to
the contrary it is a depth first exploration of the design space.

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.
