摘要
针对TCP协议的Tahoe、Reno和Vegas三个不同版本,简要描述了其所采用的拥塞控制算法,并在详细分析链路RED算法的基础上,讨论了链路RED算法下对应不同协议版本的网络数据吞吐量和端到端延迟性能。仿真结果表明,TCPVegas的综合性能最优越,但仍需在快速重传算法和拥塞控制算法上加以改进。
The congestion control algorithm on three versions of TCP is firstly described. Secondly, throughput and end-to-end delay are discussed after analyzing RED. Finally, simulating results show that TCP Vegas work best, and some improving schemes on the fast Retransmit algorithm and congestion control algorithm need to be proposed.
