In computer networking, the Stream Control Transmission Protocol (SCTP) is a transport layer protocol, serving in a similar role to the popular protocols Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). It provides some of the same service features of both: it is message-oriented like UDP and ensures reliable, in-sequence transport of messages with congestion control like TCP.
The protocol was defined by the IETF Signaling Transport (SIGTRAN) working group in 2000, and is maintained by the IETF Transport Area (TSVWG) working group. RFC 4960 defines the protocol. RFC 3286 provides an introduction.
In the absence of native SCTP support in operating systems it is possible to tunnel SCTP over UDP, as well as mapping TCP API calls to SCTP ones.

Famous quotes containing the words stream and/or control:
“One has but to observe a community of beavers at work in a stream to understand the loss in his sagacity, balance, co-operation, competence, and purpose which Man has suffered since he rose up on his hind legs.... He began to chatter and he developed Reason, Thought, and Imagination, qualities which would get the smartest group of rabbits or orioles in the world into inextricable trouble overnight.”
—James Thurber (1894–1961)
“We long for our father. We wear his clothes, and actually try to fill his shoes. . . . We hang on to him, begging him to teach us how to do whatever is masculine, to throw balls or be in the woods or go see where he works. . . . We want our fathers to protect us from coming too completely under the control of our mothers. . . . We want to be seen with Dad, hanging out with men and doing men things.”
—Frank Pittman (20th century)
