Mark Allman gave a presentation on the status of the Standard Mechanisms draft. The draft was in a similar state as at the DC meeting. FEC requires a design trade on bandwidth and processing time. Discussion from the floor on PMTU reached a consensus that PMTU should remain in the draft. It was pointed out that at some error rate smaller packets are better than bigger packets.
Satellite channels tend to have short bursts of errors then a period of clear transmission.
If there is one loss per window, then packet size doesn't matter. A larger packet size opens the window faster than smaller packets. Smaller packets are more efficient for store and forward systems. A point that was well made was that the coding design should pick the appropriate MTU for the link and that Path MTU Discovery will find it. There are some open issues with PMTU that are not limited to satellites.
