Abstract

Similar to TCP and UDP, the stream control transmission protocol (SCTP) is a transport protocol providing end-to-end communication. SCTP was originally designed within the IETF Signaling Transport (SIGTRAN) working group to address TCP´s shortcomings relating to telephony signaling over IP networks. SCTP has since evolved into a general-purpose IETF transport protocol with kernel implementations on various platforms. Similar to TCP, SCTP provides a connection-oriented, reliable, full- duplex, congestion and flow-controlled layer 4 channel. Unlike both TCP and UDP, however, SCTP offers new delivery options that better match diverse applications´ needs. Here, we introduce SCTP, discuss its innovative services, and outline ongoing SCTP-related research and standardization activities.
