Among other things, last year I've been working at an implementation of the IETF Stream Control Transmission Protocol (SCTP), which is a new internet transport protocol: an alternative to UDP and TCP, suited to carry signalling over IP.
My implementation is (by now) limited to RFC 4960 features, but this is enough to produce some basic example like the one contained in this capture file, in which one can see a complete (although short) life cycle of an SCTP association: establishment / transfer of user data / shutdown.
