On RTP filtering for network traffic reduction
Pages 356 - 359
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.

Header compression of RTP/UDP/IP packets for real time high-speed IP networks
ICHIT'06: Proceedings of the 1st international conference on Advances in hybrid information technologyIn this paper, a new header compression scheme considering BCB (Basic Compression Bits) or NCB (Negotiation Compression Bits). The header compression scheme can be used for reducing the header size by eliminated repeated fields in the packet header. ...
