Abstract :
As the use of real-time multimedia applications increases, the bandwidth available to TCP connections is oppressed by “greedy” UDP traffic and their performance deteriorates extremely. In order that both TCP and UDP sessions fairly co-exist in the Internet, UDP sessions should properly react against congestion as TCP. We implement a “TCP-friendly” rate control mechanism suitable to video applications and investigate its applicability to a real system through observation of the video quality at the receiver. It is shown through our experimental system that we can achieve high-quality and stable video transfer while fairly sharing the network bandwidth with TCP by applying our rate control at a control interval of 16 or 32 times as long as the round trip time (RTT)
