But make sure to add FRAG2 and UNICAST(2) to your config.

Yes, either generate a lot of traffic, so the switches start dropping packets, or use one of the JGroups protocols (such as DISCARD), or create your own protocol to discard random messages. > Would NS2 be my best tool to simulate something like that?

I think this will work brilliantly, especially given that this is all point-to-point unicasting, which doesn't require recipients to store messages, stability messages, distributed message garbage collection and so on ! > I expect that it will probably work fine.
