can any network simulator/emulator do this...

Hi,

I am looking for a network simulator or emulator that will allow me to create a topology with virtual hosts such as "client1" "client2", and allow me to attach my own applications to them to generate traffic. As far as I understand, NS is a network simulator that generates its own traffic by attaching agents and such, with no option for you to use your own applications to generate traffic.

Thanks!
George

Well, you can use networked virtual systems under Xen, UML or VMWare. Since you would be running complete virtual systems, you would have full control over the applications originating the data. The downside is that you would need the aggregate resources needed to run the number of virtual systems your simulation requires.

i see... because I can do most of my testing on Emulab, but whenever i want to scale to 100+ nodes, I can't hog their resources
