Package sigtran-0.9.2.3 was released under GPLv2 2007-06-24.

The OpenSS7 STREAMS SIGTRAN package includes kernel modules, SVR 4.2
STREAMS drivers, modules, libraries, utilities, test programs,
daemons, and development environment for the development and execution
of OpenSS7 STREAMS SIGTRAN applications for the SVR 4.2 STREAMS
environment.

This package contains modules and drivers formerly only part of the
Commercial releases of the strss7 package. These are commercial grade
implementations that have only recently been released as open source.

The public release currently contains the following STREAMS drivers
and modules:

- streams-m2pa_sl m2pa_sl(4)
- streams-m2ua_as m2ua_as(4)
- streams-m3ua_as m3ua_as(4)
- streams-sdl_sctp sdl_sctp(4)
- streams-sdt_sctp sdt_sctp(4)
- streams-sdt_tpi sdt_tpi(4)
- streams-sl_tpi sl_tpi(4)

This is the third open source release of the OpenSS7 STREAMS SIGTRAN
package. This release contains modules and drivers formerly only
available with Commercial releases of the strss7 package and which are
only recently available as open source with the release of this
package.

With OpenSS7 Master Package release openss7-0.9.2.D, the SIGTRAN and
SS7 over IP components were separated from the strss7 package and
placed in this package. Not all of the SIGTRAN components previously
part of the strss7 package have been strapped into this release.
Components will be re-validated against Linux Fast-STREAMS on a
module-by-module and driver-by-driver basis. See TODO in the release,
or Schedule, in the manual, for information about the release
schedule.

The major component first available is M2PA. m2pa_sl(4) is a pushable
STREAMS module that is pushed over a sctp_n(4) SCTP driver Stream to
form an M2PA signalling link providing the Signalling Link service
interface (sli(7)). A complete test suite that tests to
draft-bidulock-sigtran-m2pa-07.txt is included in the release. The
historical SS7 over IP implementations are provided, but without
conformance test suites. The release also contains simplified AS
modules for M2UA (m2ua_as(4)), M3UA (m3ua_as(4)) that as yet do not
have a conformance test suite.

Subsequent releases in 3Q 2007 will include the additional full M3UA,
SUA and TUA multiplexing drivers with conformance test suites.

Major features since the last public release are as follows:

- Dramatic performance improvements enabled by Linux Fast-STREAMS
and STREAMS SCTP.
- Support build on openSUSE 10.2.
- Support build on Fedora 7 with 2.6.21 kernel.
- Support build on CentOS 5.0 (RHEL5).
- Support build on Ubuntu 7.04.
- Updated to gettext 0.16.1.
- Changes to support build on 2.6.20-1.2307.fc5 and
2.6.20-1.2933.fc6 kernel.
- Supports build on Fedora Core 6.
- Support for recent distributions and tool chains.

This is a stable, production grade release of M2PA for Linux
Fast-STREAMS. It deprecates previous SIGTRAN component releases from
the strss7 package. Please upgrade to the most current release of
these components before reporting bugs.

As with other OpenSS7 releases, this release configures, compiles,
installs and builds RPMs and DEBs for a wide range of Linux 2.4 and
2.6 RPM- and DPKG-based distributions, and can be used on production
kernels without patching or recompiling the kernel.

This package contains modules and drivers formerly only part of the
Commercial releases of the strss7 package. These are commercial grade
implementations that have only recently been released as open source.

License Version 2'. The release is available as an autoconf tarball,
SRPM, DSC, and set of binary RPMs and DEBs. See the downloads page
