Hello,
I am a french student having a placement in BT. A part of my
project is to analyse performances of TCP over satellite connections.
At the present time, we are notably interested in windows scaling
options, how it increases throughput. The problem is that I don't
manage to trigger tcp windows scaling. I am working within HPUX 10
which is supposed to support RFC 1323 (windows scale). I have tried
with programms like netperf or ttcp to setup some big buffer size at
both end points, in order to enforce TCP end-points to use and
announce a shift count factor (in the SYN packet). But it doesn't
work. Every light on this subject would be definitvely welcome !?!
Regards,
herve
