摘要
分析了TCP和UDP协议在流媒体数据传输中存在的问题,研究了基于速率的TCP友好拥塞控制协议。针对P2P网络的特殊场景,通过应用改进的TFRC协议达到与TCP流公平竞争网络资源,并通过数据调度取得节点间一定程度的负载均衡。仿真结果表明TFRC协议有助于平稳系统的网络流量。
This paper analyzes the rate-based TCP friendly congestion control protocol.The problems of streaming media through TCP and UDP protocols are studied.An improved TRFC protocol is applied in the special scenario of peer-to-peer(P2P) network,it is reasonably fair when competing for bandwidth with TCP flows,and achieves load balance between peers in some degree.Simulation results show that the TRFC protocol is contribute to the smoothness of network traffic.
