Hmm, haven't read the paper yet, but I immediately did "Ctrl+F sctp" and didn't find anything. I know that sctp was the next generation stream-oriented protocol designed to fix the out-of-order message problem in commnications, as well as a whole bunch of connection issues (4-way handshake instead of 3-way for better open/close. Datagram oriented in-order stream, so that every packet has a proper size involved. Etc. etc.) As far as I know, sctp should solve all the requirements in section 2 of this paper (except "load balancing", which might be solved by lower-level protocol sharing of some kind?). So its weird to not see sctp discussed. -------- Yeah, sctp ain't popular, but these exact sets of problems / requirements and issues with TCP have been known for decades. SCTP, is also a decades-old protocol (though not as old as TCP), and is the most obvious solution to the problem (and already supported by Linux).
