There is a little about that in the ns manual, but as far as I know if you wnat to get the whole flow you have to single step through your code (either by hand or by means of a debugger).

(and once you have done that, write the results down and publish them in the wiki.) As a general note: understanding ns isn't quite easy. If you have to finish your project this term (assuming you are a student in the US) and have never used ns2 before this will be tough - I think so, at least.
