I am not aware of any such work going on, so I'd like to know if
anyone else is aware of work in this area?
Of possible relevance, recent FreeBSDs have SIFTR -- a kernel resident
module for collecting TCP state-machine stats (like cwnd, rtt estimator,
etc) as packets arrive and depart.
http://www.freebsd.org/cgi/man.cgi?query=siftr
This seems exactly like what I'm after.
On another note, is there software that can get mirrored traffic from
another host and do TCP analysis of flows when it comes to buffer bloat,
packet loss etc. If there was, I am in the position of running this
against a large number of customers over time and can present the results.
