SCTP Release 4
Stream Control Transmission Protocol (SCTP) is a reliable datagram-oriented IP transport protocol specified by RFC 2960. It provides the layer between an SCTP user application and an unreliable end-to-end datagram service such as IP. The basic service offered by SCTP is the reliable transfer of user datagrams between peer SCTP users. It performs this service within the context of an association between two SCTP hosts. SCTP is connection-oriented, but SCTP association is a broader concept than the Transmission Control Protocol (TCP) connection, for example.
SCTP Release 4 introduces the SCTP Stream Reset and SCTP Authentication features.
The SCTP stream reset feature enables SCTP to reset stream transport sequence numbers and all stream sequence numbers. SCTP stream reset enables SCTP to:
•Dynamically reset a peer's outbound streams
•Dynamically reset a local host's outbound stream
•Dynamically reset specific numbered streams
SCTP Authentication enables SCTP to:
•Set up a dynamic shared association key with no shared secret
•Allow a shared secret to be combined with an association key
•Use the shared association secret to authenticate chunks
•Negotiate which chunk types must be authenticated
