Thanks a lot for your response! All that seems to make sense.

Hmmm ... about time someone wrote such a tool! :)
- randomly pick a packet that carries TCP (red alert! a layer
violation straight ahead! :) )
- remember a lot of things ... state all over the place:
source/destination, sequence numbers ... but that would
only have to be done sporadically! Maybe in a separate piece
- monitor subsequent packets from the same flow - examine the
rate and sequence numbers ... it should be a little tricky,
Eventually, such a tool could be used to automatically adapt
the maximum queue length...
