Re: Ns cwnd_

Nesrine,
	cwnd_ is already implemented in ns as a tracedvariable. i.e. you could 
trace cwnd_ using something like

	$your_tcp_agent trace cwnd_
	
	when you are setting up your_tcp_agent and the "void trace(TracedVar* 
v);" function would do the job for you.
	
	Though there are other methods of tracing a variable I find this one 
most convenient. You also need to open a file and pass the file handle as a 
tclchannel to the agent. You should refer to ns-documentation to understand
how tracedvariables are used in general.

ps: cwnd_ is a floating point number in "double" format. So tracing it as %d 
would give you weird values.
