[ns] Flowmon trace format

[Ishan Mandrekar <ishan@io.ece.drexel.edu>]

Hi,

I need clarification on certain fields of the trace generated by Flow
Monitor. I make flowmon dump the statistics every 0.1s in a file:

1) what is meant by early drops?

2) Does "arrivals this flow" give the cumulative # of arrivals for a
particular flow or the arrivals measured between 2 writes (0.1s in my
case)

Does flowmon make an entry in the trace file only when there are drops in
a particular flow? I've 80+ flows in my simulation, but just 14 are
monitored inside the trace file.

Thanks,
Ishan.
