[ns] trace file for target flow

[Chengzhi Li <chengzhi@rice.edu>]

Hi,

Can anyone tell me how to get the target  flows' trace?

I run a simulation for 45Mpbs links and more than 4000 VoIP
flows in a 6 nodes topology over 60 min.  I only need to know 
the performance about target flows (only 80 flows).  Although 
I use trace-queue {n1 n2 file} to minimize the trace file, it 
is still huge.  Is it possible to only store the entries related
to target flows?

Thank you in advance.
