摘要 简要介绍了TCP Friendly的速率控制(TFRC)协议,通过仿真分析首次研究了TFRC与TCP流数之比对协议间公平性的影响。分析表明:在链路带宽较小时,无论比例如何,TFRC与TCP协议间的公平性都比较差,随着比值增大,协议间公平性得到改善;在链路带宽较大时,无论比例如何,协议间的公平性都较好,但随着比值增大,公平性能下降。 Outlines TFRC (TCP Friendly Rate Control) protocol, and deeply explores the fairness between TFRC and TCP in terms of ratio of flows. The simulation results show that under the condition of heavy network congestion, the fairness is poor for each ratio, while it becomes better with the rising of ratio, and the opposite conclusions can be obtained for light congestion.
