Zhang Hong, My own answers are
a) the IETF has a whole area devoted to transport issues, and it is very active. See http://www.ietf.org/html.charters/wg-dir.html#Transport_Area b) I'm surprised nobody has mentioned SCTP; after all it is a brand-new IETF transport protocol. See RFC 2960. c) There have been many minor upgrades to TCP in the last 5 years, in various RFCs. d) Not sure what problems there are in UDP itself.
