摘　　要：通过仿真实验的方法,研究了B-Reno协议在分组交换网络中的性能。实验使用了不同的网络拓扑和链路参数,全面考察了B-Reno的吞吐率和TCP友好性,并将实验结果与其他TCP协议版本相比较。实验结果显示,B-Reno在分组交换网络中能取得高出Reno和New-Reno10%以上的吞吐率,达到与Sack相当的水平;同时,当与Reno(传统TCP)竞争共享信道时,B-Reno也具有良好的TCP友好性。实验结果表明B-Reno在分组交换网络中也能取得良好的性能。This paper studied the performance of B-Reno over packet switching networks through experiments of simulations. Used different network topologies and link parameters in these experiments which studied the throughput and TCP-friendliness of B-Reno and compared them with those of other TCP implementations. Simulation results indicate that over packet switching networks B-Reno can achieve throughput over 10% higher than that of Reno and New-Reno, and similar with that of Sack. Meanwhile, when contends with Reno, the traditional TCP version, in shared channels, B-Reno can also achieve good TCP- friendliness. Simulation results prove that B-Reno can achieve good performances over packet switching networks.
