Abstract

At present RTP is the de facto protocol used for real time traffic in the Internet, typically running over UDP. Unless higher priority is given to RTP traffic, excessive jitter can be experienced rendering the respective packets useless at the receiver. We propose a new framework, under which such packets are identified and filtered out as soon as possible at intermediate routers, freeing network bandwidth. Our proposal is simple and scalable relative to the number of participating routers.
