Jose, all - sorry, (as I think you guessed!) my comment was about the transport services bof, not TCM-TF

For an application programmer, using protocols other than TCP or UDP is hard>> One thing I think would be useful is to analyse this as a migration problem. I know lots of people have thought about why migration is hard. My take is that the crucial issues are to make sure there is incremental benefit (the party migrating gets a benefit now and not when everyone else has migrated) and to try and ensure migration can be one party at a time (so others don't have to care - 'party' is most obviously one end host, but in some circumstances can be eg 'Apple iOS'). There's some quite nice stuff in RFC5218.

On behalf of clarity, I will send different messages with the solutions for each problem. If you think there are other problems, please start a new thread. Problems discussed in the BoF: 1) TCP multiplexing and effect on TCP dynamics. (I think this was the main problem). 2) Path MTU discovery issues 3) Are we adding latency and complexity to save relatively little bandwidth? 4) Do vendors want standards in this space? Problems discussed in the list: 5) Why is ROHC not a solution? Jose
