Abstract

The multimedia traffic of continuous video and audio data via streaming service accounts for a significant and expanding portion of the Internet traffic This streaming data delivery is mostly based on UDP However, UDP does not support congestion control mechanism For this reason, UDP causes the starvation of congestion controlled TCP traffic which reduces its bandwidth share during overload situation In this paper, we propose a new TCP-friendly rate control scheme called ”TF-RTP (TCP-Friendly RTP)” In the congested network state, the TF-RTP precisely estimates the competing TCP's throughput by using the improved parameters so that it can control the sending rate of the video streams Therefore, the TF-RTP is able to adjust its sending rate in a TCP-friendly manner and reduce a rate fluctuation Through the simulation, we prove that the TF-RTP correctly estimates the competing TCP's throughput and improves the stability and TCP-friendliness.
