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,
(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.
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.
