If you are using cisco kit you could use the saa stuff which will
simulate calls and provide you with jitter data and knock
together a few shell scripts for data collection (or use something like

Whatever this 'something' ends up being, it needs to be highly distributed -
colocated with endpoints, do call simulation, provide some reasonable means
of centrally collecting the results, and above all cheap, since dense
distribution is key. Does such a magical tool exist?

I'm trying to find out how one can measure the performance or quality of a
network for gamers and voip-users.
Both applications are very sensitive to packetloss, delays or jitter since
they're using udp instead of tcp and are very timing critical.

network ore on of your upstreams in terms of "gameability" or voip-usage?
Ordinary pings won't help since routers are regulary dropping them and
an end-to-end ping is not perfect since one of the hosts might be busy or
something like that?
Starting your favorite online game and play on a server that is being
in your own network isn't the solutions I'm looking for :-(
Your ideas are appreciated :-)
iperf is probably your best bet here, although it needs a client/server
config which isnt alway practical.
it might be worth looking at pchar
which is pretty in depth if damm slow ;)
