TCP协议两种典型拥塞控制算法的比较与仿真

Comparison and simulation of two kinds of typical TCP congestion control algorithm

计算机网络的的信息量越来越多,这必然会出现网络拥塞的情况,因而计算机网络必须进行拥塞控制从而保证数据可靠传输。TCP协议是计算机网络常用传输协议,有多种拥塞控制算法,其中TCP-Tahoe和TCP-Reno是两个典型拥塞控制算法。本文阐述了该两种拥塞控制算法的算法原理,并用网络仿真软件NS2对其进行了模拟和比较。

The rapid development of computer network makes more and more information is transmitted, it will inevitably appear network congestion, network congestion control must be conducted to ensure reliable data transmission. TCP protocol is commonly used computer network transport protocol, it has a variety of congestion control algorithm, the TCP-Tahoe and TCP-Reno are two typical congestion control algorithm. This paper describes the algorithm principle of two kinds of congestion control algorithm, and using the network simulation software NS2 to two algorithms were simulated and compared.
