link ultilization and 2-state Markov

[Joy Kongkitisupchai <joyk@CS.UCLA.EDU>]

I have two questions

1. How do I generate 2-sate Markov Chain traffic? I beleive this 
   is similar to the poisson traffic (Expoo) but it is bustier.

2. I have a network topology set up and I want to know how to
   control the link ultilization while transmitting poisson traffic?


Thanks,
