When both TCP and UDP connections co-exist in the Internet environment, the performance of TCP connections is heavily affected by the behavior of "greedy" UDP connections of real-time multimedia applications. In this paper, we propose a new TCP-friendly rate control protocol for UDP connections to fairly share the link with TCP connections. To achieve fairness among TCP and UDP connections while performing high quality video transmission, we argue that (1) the interval of rate control must be

However, the existing proposals on the TCP-friendly rate control do not satisfy all of those conditions. Through simulation experiments using the MPEG-2 video application, we show that high quality video transfer can be performed with our proposed method and the network bandwidth is fairly shared among TCP and UDP connections.
