摘要 为改善TFRC协议在有线无线混合异构网络中的性能,提出改进的TFRC拥塞控制机制,在有线网络和无线网络水平切换的条件下对其性能进行仿真分析。结果表明,在频繁切换的移动互联网中,该算法能有效利用网络资源,提高网络吞吐量,加快发送速率提升速度,从而提升TFRC的性能。 In order to improve the performance of TCP Friendly Rate Control(TFRC) protocol in wired and wireless hybrid heterogeneous network,this paper proposes an improved TFRC congestion control mechanism,and does the performance simulation under the level handoff condition in hybrid heterogeneous network.Simulation results show that the new mechanism can make use of network resources effectively,increase the throughput of network,and accelarate the increasing rate after handoff in the frequent switching mobile Internet,which effectively improves the performance of TFRC.
