Actually I'd be interested to hear what your experience is after you've tried one (or a couple) of these out. Now that our department just got a cluster of 200 linux CPUs setup I was hoping to start testing on modelnet, but it would be great to get a sense for what this involves.

ns2 is a full simulation environment. It sounds almost like David wants something more like Dummynet (FreeBSD) or NISTNet (Linux) or Modelnet (Linux?) or one of the other variants that lets you do traffic shaping/emulation. It takes some work to get them to work with virtual interfaces, and even more work to get them to work with virtual routing tables, but it can be done. The Emulab folks have done this with Dummynet on FreeBSD machines putting each node in a jail; I think others have done it by using virtual machines for the per-process encapsulation. -Dave On Jun 28, 2007, at 11:03 PM, Priyanka Sinha wrote: > ns2 ? ... there are quite a few more as well...
