    I get questions like this a lot. There isn't a lot of "aggregate"
    logic in the program because there are so many different ways to
    answer the question. It's pretty easy to add whatever you want,
    though. HOWEVER, you might find the "traffic" module handy.

    For example:

      tcptrace "-xtraffic -G" file.dmp

    will generate a lot of graphs that might help. The command

      tcptrace -hxargs

    will help you with the arguments.

    If you want something more, then it would be pretty easy to add the
    code into the mod_traffic.c file.

    Good luck!
