[ns] How to output the blocking rate?

[chenliju@msu.edu]

I have a problem:

I have added the new application and agent, and counted the blocking rate of 
packets for my case. But I could not get the blocking rate in outfile. 
Because the trace format usually is:

       event time node(from) node(to) type(pkt) size(pkt) flags fid addr(src) 
addr(dst) num(seq) id(pkt)


How to output the blocking rate? How many methods can I output the blocking 
rate?

Please let me know as soon as possible.


Thanks a lot.
