[c-nsp] network simulator

[Holemans Wim]

I'm looking for a (free) network simulator that allows me to simulate a
small network (20 switches) with different vlans on it. I want to test
different scenario's : what happens if this switch goes down or that
link goes down, how do the packets flow in each scenario for the
different vlans...

 

Anyone has a good reference to such a product ? Free would be nice but
is no absolute condition.

 

Thanks,
