[ns] TCP Session start and stops

[bsikdar@networks.ecse.rpi.edu]

hi everyone,
	i have a problem in which i am trying to simulate a number
of sessions, one after the other, between a source destination pair. 
the idea is to open a TCP connection between the source destination 
pair and

step 1. transfer a file (or a given no. of packets) between them
step 2. wait for some time say 5 seconds
step 3. go to step 1

my problem is how do i know, (other than looking in the trace file)
that my first transfer is over? and is there any way so that i can
put all this in the .tcl file for the simulator? Thanks,
