摘要
作为数据传输和Internet接入的另一种形式——卫星网络越来越受到人们的关注,其具有高时延、高链路误码率和链路不对称等特性,使得传统的拥塞控制算法并不适用于该环境,因此研究者们提出了许多改进的和新的算法。本文对这些算法进行了一个深入的总结,从卫星网络特点入手,分析了各种拥塞控制算法的原理、优点及缺点,并提出了卫星网络环境下拥塞控制的研究热点。
More and more attention is paid to the satellite networks which serve as data transmission and provide Internet access.The characteristics of satellite network such as long propagation delay,high bit error rate and asymmetric channel,make the traditional TCP congestion control algorithms inappropriate in this environment.So,many improved and new-designed algorithms are proposed.These algorithms are surveyed thoroughly in this paper.The principle,traits and deficiency of the algorithms are analyzed and finally some research issues are provided.
