In the Wireshark statistics menu, TCP stream graphs can provide a visual representation of the streams. Lisa Bock demonstrates the Time Sequence, Throughput, Round Trip Time, and Window Scaling graphs.
- [Instructor] Within the statistics menu,…there are many choices…and one are the TCP stream graphs…and those graphs will show a visual representation…of the different streams in a capture.…The one is called time sequence.…Now you have two choices with time sequence,…the Stevens graph which is a nice graph…because it graphs the TCP sequence numbers over time…and then there's the TCP trace graph…and this will visualize TCP metrics.…
It's actually similar to the TCP trace utility.…Throughput graphs the average throughput and goodput…and goodput is the actual useful data that I do receive.…Round trip time measures the time it takes to travel…from client to server and back…and then window scaling provides us with window size…and how many outstanding bytes there are…and we can see if the window size is shrinking…or growing or staying the same.…
Now I have this packet capture open…and it's purposely done because it has a lot of…good information.…Within this capture, you can see the headings…and what I'm going to add,…
