	SCTP - a Whatis.com definition
		SCTP also is intended to make it easier to manage connections over a wireless network and to manage the transmission of multimedia data.
		Like TCP, SCTP manages "reliable transport" (ensuring the complete arrival of data units that are sent over the network) over the Internet's basically connectionless Internet Protocol (IP), the protocol responsible for moving the data but not for managing whether all the data arrives.
		SCTP also supports multihoming, which means that a connected end point can have alternate IP addresses associated with it in order to route around network failure or changing conditions.

	Better networking with SCTP
		SCTP monitors the paths of the association using a built-in heartbeat; upon detecting a path failure, the protocol sends traffic over the alternate path.
		SCTP is a relatively new protocol, considering that it became an RFC in October 2000.
		RFC 3286 is An Introduction to the Stream Control Transmission Protocol (SCTP).

	[No title]
		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.
		In particular, each payload DATA "chunk" in the protocol uses two sets of sequence numbers, a Transmission Sequence Number that governs the transmission of messages and the detection of message loss, and the Stream ID/Stream Sequence Number pair, which is used to determine the sequence of delivery of received data.
		SCTP Shutdown Features SCTP Shutdown uses a 3-message procedure to allow graceful shutdown, where each endpoint has confirmation of the DATA chunks received by the remote endpoint prior to completion of the shutdown.

	Stream Control Transmission Protocol - Wikipedia, the free encyclopedia
		SCTP in contrast, conserves message boundaries by operating on whole messages instead of single bytes.
		The designers of SCTP originally intended it for the transport of telephony (SS7) protocols over IP, with the goal of duplicating some of the reliability attributes of the SS7 signaling network in IP.

		SCTP is a unicast protocol, and supports data exchange between exactly 2 endpoints, although these may be represented by multiple IP addresses.
		SCTP is rate adaptive similar to TCP, and will scale back data transfer to the prevailing load conditions in the network. It is designed to behave cooperatively with TCP sessions attempting to use the same bandwidth.
		SCTP Shutdown uses a 3 message procedure to allow graceful shutdown, where each endpoint has confirmation of the DATA chunks received by the remote endpoint prior to completion of the shutdown. An Abort procedure is also provided for error cases when an immediate shutdown must take place.

	RFC 3758 [rfc3758 - HTML version] - Stream Control Transmission Protocol (SCTP)
		Also, the SCTP receiver does not necessarily need to know which semantics of partially reliable service are being used by the sender, since the receiver's only role is to correctly interpret FORWARD TSN chunks, thereby skipping past messages that the sender has decided to no longer transmit (or retransmit).
		Stream Sequence-N: 16 bit u_int This field holds the sequence number associated with the stream that was skipped.
		When a lifetime value is indicated for a particular message and that lifetime expires, SCTP cancels the sending of this message, and notifies the ULP if the first transmission of the data does not take place (because of rwnd or cwnd limitations, or for any other reason).

	IEC: Stream Control Transmission Protocol (SCTP)
		In SCTP, data is transmitted between endpoints through a connection referred to as an "association." An association begins with an "initiation" and is maintained until all data has been successfully transmitted and received.
		SCTP closely monitors the transmission paths to the peer endpoint using HEARTBEAT chunks that test the connectivity of a path.
		In SCTP, a path is considered "active" when it has been acknowledged by the peer endpoint or has been used previously for SCTP packet transfer.

		Introduction 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 provides reliable transmission, detecting when data is discarded, reordered, duplicated or corrupted, and retransmitting damaged data as necessary.
		SCTP is rate adaptive similar to TCP, and will scale back data transfer to the prevailing load conditions in the network.

	SCTP: Stream Control Transmission Protocol Overview (RFC 2960)

		SCTP is designed to address the limitations and complexity of TCP while transporting real time signaling and data such as PSTN SS7/C7 signaling over IP network.
		SCTP is defined by IETF (http://www.ietf.org) in RFC 2690.

		SCTP is connection-oriented in nature, but the SCTP association is a broader concept than the TCP connection.
		In SCTP it is used by an endpoint to validate the State Cookie information that is returned from the peer in the COOKIE ECHO chunk.
		On a multi-homed host, an SCTP endpoint is represented to its peers as a combination of a set of eligible destination transport addresses to which SCTP packets can be sent and a set of eligible source transport addresses from which SCTP packets can be received.

		SCTP is a key piece of the puzzle for making IP a truly viable technology choice in building the next-generation commercial grade infrastructure for telecommunications and e-commerce.
		When we first brought the original idea of SCTP (then called MDTP) to the IETF, we were trying to create a protocol to solve a very particular and practical problem; that is, how to transport telephony signaling messages using IP technology in commercial-grade systems.

		Stream Control Transmission Protocol (SCTP), defined by the Signal Transport (SIGTRAN) working group of the Internet Engineering Task Force (IETF), is a transport level datagram transfer protocol that operates on top of an unreliable datagram service such as Internet Protocol (IP).
		An SCTP association is comprised of multiple logical streams, ensuring the sequenced delivery of user datagrams within a single stream.
		Although SCTP is designed to carry PSTN signaling information over the IP network, its generic design can be utilized to provide a reliable transport delivery mechanism for other multimedia and wireless frameworks such as H.323, SIP, Wireless and so on.
