A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : LoWPAN simple fragment Recovery Author(s) : P. Thubert Filename : draft-thubert-6lowpan-simple-fragment-recovery-03.txt Pages : 11 Date : 2009-03-23 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.
