Research on Congestion Control of Real-Time Multimedia Unicast
Qing Xiong · Wuhan University Journal · 2004
This paper makes a brief analysis on the disadvantage of TCP-like rate control scheme for real-time multimedia service,and presents a RTCP-based congestion control mechanism which is stable and TCP-friendly.This mechanism makes the rate vary smoothly and it is fit for real-time multimedia applications.Lastly it makes a simulation through NS to evalue the performance of RAP and RCC,which lays a strong emphasis on the study of TCP-friendliness.The experimental results show that RCC mechanism,in most of scenarios:bottleneck link bandwidth varied,delay varied and loss ratio varied,is more TCP-friendly by contrast with RAP.
