Hello colleages, 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. ==> Which tools (under linux) are you using in order to measure your own 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 even 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 housed in your own network isn't the solutions I'm looking for :-( Your ideas are appreciated :-) Gunther
