Title : LoWPAN simple fragment Recovery
Author(s) : P. Thubert
Filename : draft-thubert-6lowpan-simple-fragment-recovery-02.txt
Pages : 12

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.
