Header Compression Code

This toolkit uses high-level descriptions of various protocols to generate Linux C source that implements appropriate header compression algorithms for them. Further introductory information can be found in our MobiCom 2000 paper, A Unified Header Compression Framework for Low-Bandwidth Links.

The implementation below is targeted for Linux 2.0.36 using the PPP 2.3.5 communication layer. Further ports are possible; the idea is to use a single, platform-independent description of a protocol in conjunction with this toolkit which may be ported to many platforms.

Our toolkit:

• <headertoolkit.tar.gz> (GPLed, see README file for more details)

Required software:

• Linux 2.0.36
  (2.2.x and later kernels won't work with this version, since the PPP stack was restructured in the Linux 2.2 kernel).
• PPP 2.3.5 distribution (freely distributable)
  This is required to produce a modified PPP daemon which is capable of using the compression extensions.
• Jeeves (freely distributable)
  A Perl-based toolkit to help automated code generation which we used in this project.
