Trace Questions

["Emad A. Qaddoura" <eaq@faith.mynet.net>]

Hi,

     In ns manual, the +, -, d are mentioned as the first column in the
trace,
     but in out-bw, I could not find the how to fully interpret the
following output.

out.bw
tcp.0.0.1.0 99.158800 XXX 7.361929 58.895428
tcp.0.1.2.0 99.989700  XXX 6.630683 53.045464

What is the XXX number (I had a number there)

 2 111.451480 2 0.5Mb 0.1ms LL Queue/DropTail Mac/Csma/Ca Channel 0 +172
-150 d2 l13 r160

    What is "l" what does l13 mean?

     Is the effective throughput indicated by r160? and is "r" mean
successfuly received?

What is the correct syntax to generate xgraph for a sample of out.tr

Your help is greatly appreciated.
