Introduction ------------ This piece of software is an implementation of RObust Header Compression for Linux (or other Unix-compatible OS). The library can be used to add ROHC compression/decompression capabilities to an application. Official website: http://rohc-lib.org/ Mailing list: rohc@lists.launchpad.net Mailing list archives: http://lists.launchpad.net/rohc/ Bugtracker: http://bugs.launchpad.net/rohc License ------- The project is licensed under the GNU LGPL version 2.1 or later, see the COPYING and AUTHORS files for more details. Some network captures or small scripts used for testing are under the GNU GPL version 2 or later. Libraries --------- The sources are in the src subdirectory. The sources are separated into three libraries: - a library that contains the routines used for both the compression and the decompression processes - a library that handles the compression process - a library that handles the decompression process See the INSTALL file to learn to build the libraries. Automated tests --------------- The test subdirectory contains several test applications. See the INSTALL file to learn how to use these tools. Statistics ---------- The statistics subdirectory contains an application that generates some compression statistics. The generate_statistics.sh script outputs a HTML report with the statistics results. The Gnuplot tool is required. See the INSTALL file to learn how to use the statistics application and the generate_statistics.sh script.

A library for the RObust Header Compression (ROHC) protocol. It provides an easy and robust way for applications to reduce their bandwidth usage on network links with limited capacity or expensive costs. Headers of network packets are compressed with the ROHC protocol and algorithms.
