在讨论TCP拥塞控制算法的前提下,对TCP的拥塞控制算法性能进行了仿真分析。仿真和实际测试结果表明:由于无线环境中的数据传输存在非拥塞引起的丢包,随着无线链路中随机数据包丢失概率的增加,TCP很难提供高效的无线Internet接入,拥塞控制算法将导致无线网络性能的严重下降。 Under the premise of discussing TCP congestion control algorithm, the performance of TCP congestion control algorithm is simulated. Simulation and actual test results show that due to the non-congestion caused packet loss due to data transmission in wireless environment, it is difficult for TCP to provide efficient wireless Internet access as the probability of random packet loss in the wireless link increases. The congestion control algorithm Will result in a serious decline in wireless network performance.
