Abstract :
Typically, VoIP traffic is deployed as best-effort traffic over Internet links. This voice traffic lacks effective and scalable end-to-end congestion control. We propose a new VoIP congestion control scheme called Voice-TFCC (voice TCP-friendly congestion control), that tries to keep the transmission protocol overhead to a minimum while maintaining a TCP-friendly throughput. Voice-TFCC adjusts packet and codec rate in order to reduce the traffic load non Internet routers and the overall header bandwidth used by VoIP. We used analytical results to show the bandwidth efficiency obtained through our proposal. Voice-TFCC scheme is scalable because no changes are needed at core routers and minimal control messages are used and thus can be easily implemented and deployed in todaypsilas Internet.
