Are there any other (open > source) implementations of it? SCTP in KAME is complete, stable and fully supported. It is mainly developed by the SCTP RFC author, Randall Stewart. A T/TCP alternative as you are describing sounds very similar to PR-SCTP (Partial Reliability SCTP). (Don't let the name fool you, please read the internet draft). There is at least another kernel-level open source implementation, for Linux, plus other user-level implementations. marco -- panic("The moon has moved again.");
