I guess I should be more specific: The "simulator" is a dual-homed machine running Linux, sitting between a couple test servers and a bunch of workstations: Servers------Simulator--------Workstations Physically, the network is a mix of GigE and FastE. The delay, loss and bandwidth constraints must be applied to all traffic going through the simulator. For now, there's no need to differentiate between the various protocols, addresses, etc. - everyone is equal. The simulator is a plain router, nothing fancy. At most, it might NAT the addresses of the servers to IP aliases on the interface facing the workstations. -- Florin Andrei http://florin.myip.org/ _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
