Hi everyone,
Below is a summary of changes in this draft. Please send comments.
Thanks.
1) Specify use of context 0 when CID is 0.
- addresses ticket #32
2) Made prefix-based multicast encoding format more explicit for
clarity.
- addresses ticket #33
3) Indicate that first 64-bits is link-local prefix padded with zeros
when link-local prefix is elided.
- addresses ticket #34
4) Full 128-bit address inline only in stateless encoding.
- Removes encoding redundancy and doesn't make sense to allow a non-
stateful mode when stateful compression is specified.
5) Removed support for compressing unspecified address.
- Falls out of change (4). Unspecified address probably won't be used
much since we are changing how DAD works in 6LoWPAN networks.
6) Added support for IPv6 Extension Headers as well as IP-in-IP with
new LOWPAN_NHC encodings.
- Mostly what we talked about at the SF meeting.
7) Allow for completely stateful compression.
- Changed wording around stateful compression so that inline bits can
be used as an additional index to identify the compressed address.

successfuly submitted by Jonathan Hui and posted to the IETF
repository.
Filename: draft-ietf-6lowpan-hc
Revision: 05
Title: Compression Format for IPv6 Datagrams in 6LoWPAN Networks
Creation_date: 2009-06-30
WG ID: 6lowpan
Number_of_pages: 19
Abstract:
This document specifies an IPv6 header compression format for IPv6
packet delivery in 6LoWPAN networks. The compression format relies
on shared context to allow compression of arbitrary prefixes. The
information that is maintained in that shared context is out of
scope. This document specifies compression of multicast addresses
and a framework for compressing next headers. This framework
specifies UDP compression and is prepared for additional transports.
