[Pppext] draft-jurski-pppext-iphc-00.txt

[Janusz Jurski <jjurski at eti.pg.gda.pl>]

Hi All,

I have submitted the following Internet draft: 
http://www.ietf.org/internet-drafts/draft-jurski-pppext-iphc-00.txt. The 
document adds an extension to IP Header Compression negotiation for PPP. 
The abstract of the document is as follows:

  This document extends RFC 3544 (which extended its predecessor,
  RFC 2509) by specifying additional negotiation options to PPP Control
  Protocols for IPv4 and IPv6 (see RFC 1332, RFC 2472).  The
  negotiation options specified in RFC 2509 defined an all-or-nothing
  strategy for applying header compression: peers were assumed to
  support compression for any combination of headers.  RFC 3544 refined
  that strategy to make it possible to negotiate header compression for
  only TCP or only non-TCP packets.  The current document further
  refines the strategy by also making it possible to negotiate header
  compression for only particular combinations of headers or header
  types.

I would like to discuss the proposal / request your comments. Note that 
the most of the document is copied from RFC 3544 (and RFC 2509). A new 
suboption is defined in Section 2.5. Section 5.2 explains the reasons 
for this new suboption and discusses the advantages and disadvantages.

Kind regards,

Janusz
