Hi all, Any thoughts on products that screw up networks in deterministic (and realistic found-in-the-wild) ways? I'm thinking of stuff like PacketStorm, Dummynet, etc. Dial up jitter, latency, tail drop, RED, whatever... (I know someone's gonna say "Just buy a Brand Z FubarSwitch 3k, they will screw up your whole network and you don't even have to configure it to do so!") I'm all-ears like Ross Perot. Thanks, -r
Definite +1 for dummynet on freebsd; I've used in the lab at layer 2 in bridge mode, and layer 3 both, for doing testing. latency introduction is good down to a few ms, but isn't accurate below that--but for most of what we do, in terms of simulating latency and loss/jitter, it works like a charm.
