Dear all:

draft-thubert-6lowpan-simple-fragment-recovery-03 is off the press.
No real change from layer 2, mostly a refresher for the toolset and a few typos.

A new version of I-D, draft-thubert-6lowpan-simple-fragment-recovery-03.txt has been successfuly submitted by Pascal Thubert and posted to the IETF repository.

Filename:	 draft-thubert-6lowpan-simple-fragment-recovery
Revision:	 03
Title:		 LoWPAN simple fragment Recovery
Creation_date:	 2009-03-23
WG ID:		 Independent Submission
Number_of_pages: 11

Abstract:
Considering that 6LoWPAN packets can be as large as 2K bytes and that
an 802.15.4 frame with security will carry in the order of 80 bytes
of effective payload, a packet might end up fragmented into as many
as 25 fragments at the 6LoWPAN shim layer.  If a single one of those
fragments is lost in transmission, all fragments must be resent,
further contributing to the congestion that might have caused the
initial packet loss.  This draft introduces a simple protocol to
recover individual fragments between 6LoWPAN endpoints.
