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.

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.
