SCTP

Stream Control Transmission Protocol


From RFC 3286 :An Introduction to the Stream Control Transmission Protocol (SCTP)

The Stream Control Transmission Protocol (SCTP) is a new IP transport protocol, existing at an equivalent level with UDP (User Datagram Protocol) and TCP (Transmission Control Protocol), which provide transport layer functions to many Internet applications. SCTP has been approved by the IETF as a Proposed Standard. The error check algorithm has since been modified. Future changes and updates will be reflected in the IETF RFC index.

Like TCP, SCTP provides a reliable transport service, ensuring that data is transported across the network without error and in sequence. Like TCP, SCTP is a session-oriented mechanism, meaning that a relationship is created between the endpoints of an SCTP association prior to data being transmitted, and this relationship is maintained until all data transmission has been successfully completed.

Unlike TCP, SCTP provides a number of functions that are critical for telephony signaling transport, and at the same time can potentially benefit other applications needing transport with additional performance and reliability.
