SCTP

The Stream Control Transmission Protocol (SCTP) is a Transport Layer protocol, serving in a similar role as the popular protocols Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Indeed, it provides some of the same service features of both, ensuring reliable, in-sequence transport of messages with congestion control.

In a nutshell, SCTP was selected by the SIGTRAN IETF workgroup mainly because of these features:

• Connection oriented - Establish connection between endpoints.

• Reliable transport - Enable acknowledgment of data.

• Multiple streams - Separate data in independent streams of chunks in parallel.

• Ordered delivery - Guaranties order of data from each stream independently.

• Congestion control - Congestion control is stream independent.

• Multi-homing support - Enables transparent fail-over between redundant network paths.

TelcoBridges and SCTP

TelcoBridges supports SCTP as a mandatory component of its SIGTRAN implementation.
