TCP connection analysis
i need to see how congestion window increases with every received acknowledgement in tcp connection.
The tcp connection details were captured using tcpdump. Is there a way where in I can plot a graph between congestion window and number of acknowledgement received using data captured with tcpdump ?

hi sunnycoder
i am not interested in timesequence graph. There are many utilities like ethereal,tcptrace where time sequence graph can be plotted.
what i need is plotting of congestion window vs no of acknowledgement received.

Should have read a bit more carefully. I could not locate a utility that does what you want (not sure if some of the common ones can handle it). A possible way will be to write scripts to extract the information from tcpdump data pass it to gnuplot.

what you have stated is perfect and it this precise behaviour i need to check in a TCp coneection. From this point onwards i intend to hack the linux kernel and change the behaviour of increse of congestion window. thus the concept as it is in place, could be theoriticaly depicted by a graph. (increase of congestion window). I am looking for a way to do so using output of packet sniffer say tcpdump.
Thus the above stated explanation is theory of what i am intending to depict graphicaly.
