Simulating real traffic.

[Shekhar A Amlekar <saa@csa.iisc.ernet.in>]

Dear ns-users,
	How do we simulate real traffic in ns ?

	I am implementing an algorithm which requires the n/w traffic
	to be as close to the one that exists.

	i.e I want the end-to-end delay to be stochastic with some 
	spikes of the type 
		
			.
			 .
		         .
			  .
			  .	
	..........	   ......

	which generally occur.

	I tried using expo sources but instead of observing spikes of 
	the above type I observed increasing delay spikes like

		      .	
		     .
		     .
		    .	
		    .
	............	............

	
	Can you suggest some tech. to obtain the desired char ?


Thanks
Shekhar
