Trace TCP State variables while using nsc

[Ashwin Rao]

Hi,

I am interested in addressing the problem of monitoring the TCP state
variables such as the TCP congestion window, and RTT while using nsc.
I would like to know if any one can give some pointers on making the
tp->snd_cwnd available to nsc. Are there any issues why this is not
possible? If this is possible, can anyone give a broad picture as to
what needs to be done. I believe having some insight would be really
useful.

Regards,
Ashwin

PS: I had posted a similar query a few months ago regarding monitoring
the congestion window [

].

Is there a reason why the answer you got back then is not applicable
to this variable you are interested in ?
