CSLIP won't help very much in that its designed to do header (not data)
compression. It has several drawbacks
o It needs quite large (in PC NOS terms) tables to track the compressed
headers.
o It compresses message headers not the packet data. This is at its best
with things like telnet down a slow serial line.
o Only some packet headers are compressed. In paticular many types of
resend (common on radio alas) are not compressed.
It may help in places - ack frames will be smaller in paticular.

All,
I had this idea last night, why not use Van Jacobsen TCP/IP header
compression on AX.25 frames. Obviously, as an AX.25 interface isn't point
to point, a machine would need structures for every destination that it is
TCP connected to. Apart from that, I can't see any major obstacles.
Comments? I think it would be very useful on slow speeds ( < 9.6kbps).
Once AX.25 code becomes available for 386bsd/BSD386/Net-2, I'll modify the
existing cslip code and try it out.
Cheers all,
Warren

Yep, there is a patch to Thenet X-1H that fixes this problem. Don't
have it handy right now but I can send you the patched version if you
like.
