title: Plot RTT histogram using wireshark or other tool
body: <p>I have a little office network and I'm experiencing a huge internet link latency. We have a simple network topology: a computer configured as router running ubuntu server 10.10, 2 network cards (one to internet link, other to office network) and a switch connecting 20 computers. I have a huge tcpdump log collected at the router and I would like to plot a histogram with the RTT time of <strong>all</strong> TCP streams to try to find out the best solution to this latency problem. So, could somebody tell me how to do it using wireshark or other tool?</p>
