摘要: 提出了一种新的适用于异构网络的传输控制协议(TCP)算法。该算法不仅能够动态寻求网络中的性能最优点,尽量使网络流量保持在该点,而且能够判断网络中数据包丢失的原因,合理地调整参数,避免了TCP-Reno中盲目将发送窗口减半的机制。仿真实验的结果表明,新算法的性能优于TCP-Reno和其他同类改进协议。

Abstract: A new TCP algorithm that was applicable to heterogeneous networks was proposed. It can not only find the best point in performance and keep the network load around it, but also determine the reasons of dropping packets and adjust parameters reasonably to avoid the mechanism of blind halving congestion window in TCP-Reno. The experimental results show its performance is better than TCP-Reno and other improved protocols of the same kind.
