Dear all,

We are proud to announce the release of an updated version of the GPL ROHC
In the frame of a project involving the french space agency (CNES), Thales
Alenia Space (TAS) and Viveris Technologies (+ some internal work from TAS
and a collaboration between TAS and Viveris), various new features have
been added to the GPL stack initially developped by Martin Juhlin
This includes mainly:
- RTP profile
- IPv6 support
- tunneling support
- new improved packet classifier
- test and statistics tool to analyze the ROHC behavior
- non regression tool
- standalone library in user space
- context reset, fixed packet sizes, (basic) list compression support
- uncompressed profile now working
- various bug corrections and code cleanup

(See attached file: Compliance.rtf)

Moreover, a new branch will bee created with several performance
enhancements (leading to a dramatic reduction of the processing time per
packet), as well as the support of constant IP-ID (§3.3 RFC 3843), that are
currently under development.

The site will be hosted by launchpad :

(In principle, the site will be available in few days, thanks to Didier

Please feel free to comment or contribute to the code. Hope this will help
to develop a completely free and compliant ROHC implementation
