[Lwip] fragment forwarding implementation and performance report

<sending to 6lo, lwig WGs because both have relevant drafts>



Hello All,


We tried experimenting with the virtual reassembly buffer and fragment
forwarding drafts.

One fundamental characteristic that has major implications on fragment
forwarding performance is its behavior with realistic 802.15.4 RF
(especially when a train of fragments are simultaneously received and
transmitted). This is something which was not evaluated in any other
experiment.



You ll find the details of the implementation, test setup details and
performance result here:

https://github.com/nyrahul/ietf-data/blob/rst/6lo-fragfwd-perf-report.rst



Results are quite interesting: Simultaneous send/recv of fragments with
fragment forwarding has major implications on PDR/Latency.



Feedback most welcome.



Thanks,

Rahul
