In a nutshell

Our purpose is to provide a quick directory to all things related to Signal Transport technology.

What's new?

We are very pleased with our new webhost SiteRise.

Tekno Telecom NetAnalyzer added to the Tester Product section. Hi Sam!

The M2UA draft on test specifications has been updated in June of 2006.

There is a link to the TietoEnator Signal Gateway that uses the SIGTRAN protocols.

What is SCTP?

Here's a tutorial (not for dummies or idiot's) that integrates the author's comments with material taken from RFC2960. The links within the document make for a better navigation experience than reading the RFC in text format.

Here's a list of more tutorials:

Standards bodies
IETF-SIGTRAN
The focus group. Get RFCs here (RFC 2960).
IETF-TSVWG
The group with a wider interest in transport protocols - most notably, the TCP/UDP/IP protocols.
Open source
SCTP
implementations
An kernel implementation of SCTP. Also has some of the adaptation layers.
Linux Kernel Implementation
An implementation of SCTP that is being woven directly into the Linux kernel at the same level as TCP and UDP. Actively being developed.
Siemens/University of Essen
A site full of information and links to the RFCs describing SIGTRAN protocols. It is sponsered by Siemans and the University of Essen, a group that produces the sctplib user space implementation of SCTP. Last update 2005-03-04.
OpenSS7
A new release is available of the the SCTP part of the project. It is based on a forked version of Linux STREAMS.
Reference Implementation
No longer available at this website. The author of the Reference Implementation, Randall Stewart, and Qiaobing Xie, have written a book fittingly entitled "SCTP" that was well received by the SCTP community.

ns-2 SCTP module by UoD P.E.L.
SCTP testing/simulation by the Protocol Engineering Laboratory at the University of Delaware.
RivuS
SCTP on BSD development effort by some folks at the Pune Institute of Computer Technology.
KAME
SCTP on BSD development effort by a consortium of companies in Japan
Sun SCTP
An implementation in the Solaris kernel.
Open source
adaptation
layer
implementations
M3UA on Sourceforge
Uses UDP as the transport layer out of the box. Conversion to SCTP is straightforward according to documentation. Compiles cleanly out of the box. Nice documentation. Well worth a look. Go to the last page of the .pdf to see a graphic of the architecture. A management layer figures in prominently.
SCCP User Adaptation (SUA)
This implementation is used in conjunction with the sctplib open source SCTP implementation.
OpenSS7
Offers a suite of user adaptation (UA) layer protocols that are compatible with the SCTP implementantion. Probably embedded in the SCTP tarball but this is not known authoritatively.
Tools
sctpperf
A client/server benchmark tool that can be used to measure the performance of SCTP connections
SCTP Test Tool (stt)
Built by the sctplib folks.
Other sources
of information

The open source SUA implementation author's homepage is worth a visit. Be sure to visit the history links.

Since SCTP is interesting to those also interested in telephony signaling, it seems appropriate to have a reference on C7/SS7. This site is a collection of links from names commonly associated with C7/SS7. Unfortunately, a growing number of links are going stale. We'll create our own list in the near future.

SIGTRAN and SIP protocols are related to the emerging technology of Voice over Internet Protocol (VoIP) that may replace today's switched telephone networks. The SIGTRAN protocol is an important tool for bridging the existing SS7 signaling network to the VoIP networks.

Conformance
Performance
Research

A published SCTP Performance Test for lksctp is made possible by the DataTAG project.

The bakeoff is now known as the plugtest. Groups attend, results are owned by and published by the participants.

If you're interested in a bakeoff you should look here.
