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.
