Well i'm out this days but i'll try to test again when i go back home, I'll send the scripts later this week. I have 3 PCs, something like this: A<=3D=3D>R<=3D=3D>B Where R is the router with 2 ethernet cards...so i have in A a http server (tcp) and VLC streaming (udp) to B, i think i can control the outgoing traffic from A to B in the "R"outer. You are saying to me that with this configuration if the rates/ceils are well chosen, the video streaming must work with no jerks even if the bandwidth is at 100% (or near).
