| 摘 要： | 针对互联网中高速长距离网络上的拥塞控制问题,基于同步AIMD源在Drop-Tail网络环境下竞争带宽的网络模型,提出了一个新的AIMD拥塞控制算法,I-TCP。通过合理地设计高速和低速模式以及模式切换规则,使得该算法适合于配置到高速长距离网络,同时在传统低速网络中也具有很好的性能。仿真试验表明,I-TCP中的AIMD算法在高速长距离网络中表现出了很好的效率、公平性和网络响应性。

| Abstract: | To investigate the problem of the congestion control over high-speed long distance networks,this paper presents a new AIMD congestion control algorithm,I-TCP,which is based on a model of network of synchronous AIMD sources competing for a shared bandwidth under drop-tail queuing.With a reasonable design of a high-speed mode,a low-speed mode and the mode switch rule,I-TCP is suitable for deployment in the high-speed long distance networks as well as the traditional low speed networks.Simulation experiments show that the AIMD algorithm of I-TCP performs better than current TCP implementations in terms of efficiency,fairness and network responsiveness over high-speed long distance networks. |
