Stream Control Transmission Protocol (SCTP)


Overview:-	The SCTP transport component is an implementation of the Stream Control Transmission Protocol (RFC 2960) for both Linux Native and STREAMS, as well as a STREAMS interface to the Linux Native implementation. SCTP is a fundamental component of the Signalling Transport (SIGTRAN) working group Signalling User Adaptation Layers (UAs). As such, this SCTP transport component is a fundamental underpinning to the SIGTRAN UA implementations (IUA, DUA, GR303UA, M2PA, M2UA, M3UA, SUA, TUA, ISUA, BUA).

History:-	Work on the SCTP transport component began in January 2001.

Status:-	The Linux Native release of SCTP is in the Maintenance stage. The STREAMS release of SCTP is in the Maintenance stage. The STREAMS TPI interface to the SCTP Linux Native release of SCTP is in the Maintenance stage.

Dependencies:-	The current Linux Native release depends on a Linux 2.4.x kernel and does not depend on any other OpenSS7 components. The deprecated Linux Native release depends on a Linux 2.2.x kernel and does not depend on any other OpenSS7 components. The STREAMS release depends on a Linux 2.4.x kernel and a current LiS (e.g. 2.16.16) and does not depend on any other OpenSS7 components. The STREAMS inet interface release depends on a Linux 2.4.x kernel and a current LiS (e.g. 2.16.16) and depends on the Linux 2.4.x native release above. This INET interface package is an integral component of current LiS releases and need not be downloaded separately.

Design:-	Designs for the SCTP components can be viewed here.

Code:-	Code for all three SCTP components has been publicly released and code for these components can be viewed in the following locations: LiS STREAMS version Linux Native version STREAMS TPI access to Linux Native version SOCKETS access to the STREAMS version Maintenance and feature enhancements updates are normally publicly released as soon as they become available.

Documentation:-	Documentation for the SCTP TPI component is available here. The SCTP man pages are available as follows: LiS STREAMS TPI and NPI interfaces: npi_sctp(7), tpi_sctp(7), xti_sctp(3), LiS STREAMS TPI interface to SCTP NET4: tpi_sctp(7), SCTP NET4 Sockets Interface: sctp(7).

Test Results:-	OpenSS7 has participated (and will continue to participate) in testing events for the SCTP component. These are: 2nd SCTP Interoperability Test - ETSI, 2001 6th SCTP Interoperability Test - Delaware, 2003 Test programs and test results have been publicly released and are part of the public release packages. Performance test results for the Linux Native SCTP implementation are available on this website under: SCTP Performance.
