This document obsoletes RFC 2960 and RFC 3309. It
describes the Stream Control Transmission Protocol (SCTP). SCTP is
designed to transport Public Switched Telephone Network (PSTN)
signaling messages over IP networks, but is capable of broader
applications.
SCTP is a reliable transport protocol operating on top of a
connectionless packet network such as IP. It offers the following
services to its users:
-- acknowledged error-free non-duplicated transfer of user data,
-- data fragmentation to conform to discovered path MTU size,
-- sequenced delivery of user messages within multiple streams, with
an option for order-of-arrival delivery of individual user
messages,
-- optional bundling of multiple user messages into a single SCTP
packet, and
-- network-level fault tolerance through supporting of multi-homing
at either or both ends of an association.
The design of SCTP includes appropriate congestion avoidance behavior
and resistance to flooding and masquerade attacks. [STANDARDS TRACK]
