中文摘要：

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。

英文摘要：

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.
