A Multiplexing-Based TCP-Friendly Congestion Control Mechanism for Multimedia Streaming Applications

This paper focuses on the tradeoff between the TCP-friendliness and the minimum rate threshold of multimedia flows in multiplexing environments,and proposes a multiplexing-based TCP-friendly rate controlling algorithm-MTCRC.It keeps the average throughput of multimedia flows friendly when they are multiplexing and the friendly rate is lower than the restricted minimum rate by hanging up some flows on proper occasion.It also improves TFRC(TCP-friendly rate control) and maintains the favorable rate smoothness of TFRC.Meanwhile the characteristic of the minimum-rate threshold of multimedia flows and multiplexing environments are taken into consideration,so MTCRC can keep multimedia flows available,share bandwidth fairly with TCP flows.The results of simulating show that MTCRC outperforms TFRC.
