(lots of deleted stuff)
I'm not sure what kind of ATM simulation Dapeng is attempting to do, but
if ATM is being treated as essentially a MAC layer, I don't see why
you can't add it to ns-2. Though I had to admit it, I wrote some
segmentation and reassembly agents for my own version of ns-1. There was
no ATM signalling included since the MAC I was simulating was just using
the cellification of ATM. It would be a moderate amount of work to do
an ATM MAC, but I don't see any reason why it couldn't be done.
