摘要
TCP (transmission control protocol,传输控制协议)通过估计网络的特性和条件,采用了一些有效利用网络资源的技术。慢启动算法是有效利用资源的主要技术。慢启动的目标是快速地为网络路径建立一个最佳状态的TCP连接,除非给网络带来过多的负载。但在卫星链路等大带宽、长时延链路中,慢启动算法不能正常工作,导致性能大幅下降。本文讨论了大带宽、长时延网络中当前慢启动算法存在的问题。提出了一种新的慢启动算法,可以提高大带宽、长时延网络的网络传输性能。我们还在网络模拟器上实现了该算法进行评估,与普通慢启动算法相比,它的效率超过60%。
Smooth slow-start: refining TCP slow-start for large-bandwidth with long-delay networks
The transmission control protocol (TCP) adopts some techniques that use network resources efficiently by estimating the characteristics and condition of the network. The slow-start algorithm is the primary technique for effective resource usage. The goal of slow-start is to establish a TCP connection in an optimum state for the network path quickly unless giving an excessive load to the network. However, in large-bandwidth with long-delay links such as satellite links, the slow-start algorithm does not work properly and causes substantial performance degradation. In this paper, we describe the problem of the current slow-start algorithm in large-bandwidth with long-delay networks. We propose a new slow-start algorithm that can increase network transfer performance for large bandwidth with long delay networks. We also implemented this algorithm on a network simulator for evaluation and it resulted in over a 60% efficiency compared to a normal slow start algorithm.
