[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: multiple TCP connectionsWe recently completed work on a transport protocol with multi-homing support, plus support for multiple information streams within one session. If this might be of interest (it was built for transport of signaling and control messaging) folks can find it at http://www.ietf.org/internet-drafts/draft-ietf-sigtran-sctp-13.txt . It was recently approved as a Proposed Standard and is on the RFC editor's queue. Cheers, L.
