Re: [ns] Variable Bit Rate Source

[Shantanu S Bhardwaj <shantanu@ee.eng.ohio-state.edu>]

u can also use a heavy tailed source (expoo or pareto) as your traffic
source .. usea udp agent and use a random variable to  set  the value of
the burst time and/or size of ur packets...
this can simulate a vbr source ...
