I did have NIST ATM Network Simulator.  It's a powerful simulation for
ATM network.  But its function in simulating TCP/IP traffic is very
limited compared with ns-1 and ns-2.  

What I'm concerned with is a hybrid IP/ATM networks since the
integration of IP router and ATM switches is a very important research
area right now.  I'm not sure if ns-2 developers have  interest in
adding ATM stuff to it so that it can be more powerful and useful.
