Realised yesterday that my little old undergrad project was lost to the world. So here it is again.
‘Pneumatic IP’ is a module for the later 2.4 series of the Linux kernel that implements net-
work segment compression according to RFC3173 (IP Payload Compression using Deflate).
‘Pneumatic IP’ exchanges compressed network traffic between hosts that support RFC3173.
It is transparent to all network applications on either end-point (excepting applications such
as ngrep or tcpdump). With an IPComp driver loaded, client and server applications need no
modification to be compatible with RFC3173.
