(Don't let the > name fool you, please read the internet draft). Can you sketch this in a bit more detail? I do not follow. PR-SCTP is about being allowed to "abandon" data --- i.e., send it and then decide that you don't really care if it gets across the network (say, because it got lost and has taken too long to retransmit and so the data is out of date). Without a Big Hack, I cannot envision TCP doing something like this. What am I missing?
