Randall Stewart of Cisco Systems gave a talk titled SCTP, what it is and how to use it, discussing the Stream Control Transmission Protocol (SCTP). A paper that was displayed on the overhead projecter before the talk began summarized:

"Integrated into FreeBSD 7.0 -- first standardized by the Internet Engineering Task force (IETF) in October of 2000, in RFC 2960 and later updated by RFC 4960. SCTP is a message oriented protocol providing reliable end to end communication between two peers in an IP network."

Randall explained that SCTP is an alternative protocol to TCP, UDP. To describe SCTP, he suggested you start with TCP features, including: reliable retransmission, congestion control, flow control, connection oriented, and selective acknowledgements. You then add to it more features, including: "association" 4-way handshake, framing and ordered service, multistreaming, multihoming, and reachability.
