摘要
随着Internet的普及和规模的快速增长，近些年来，有相当多的研究都试图扩展Internet的体系结构。其中，更多、更合理的控制机制对已有的网络稳定运行无疑将是至关重要的。其中一个最基本和最重要的要求就是防止网络出现拥塞崩溃，使网络运行在轻度拥塞的最佳状态，同时保证一定的公平性。从用户需求的角度来说，网络必须为所有用户的请求提供服务，然而用户的需求在传输起始时间、需求速率、持续时间上变化很大，在很多情况下还是突发的。从网络提供资源的角度来说，任何网络物理资源都有固定的上限能力。因此，用有限的资源去适应波动很大的用户需求，一定会出现网络资源不能满足用户的需求的时候，此时就必须使用拥塞控制来管理用户流量对瓶颈资源的共享。
本文从拥塞控制的概念，拥塞控制的方法等几个方面对计算机网络的拥塞控制进行一个粗略的概述。

Abstract
With the popularity of the Internet and scale, the rapid growth in recent years, A large number of studies have tried to expand Internet architecture. Among them, more and more reasonable mechanism to control the network has been stable operation will undoubtedly be crucial. One of the most basic and most important requirement is to prevent the emerging network congestion collapse so that the operation of the network congestion in the best mild state, but a guarantee of equity. Demand from the users point of view, the network for all users must be provided at the request of services, However, the demand of users in the initial transmission time, the demand rate, duration, enormous changes, In many cases or emergencies. Provide resources from the network point of view, any network physical resources have fixed the maximum capacity. Thus the use of the limited resources to adapt to fluctuations in demand for large users. will have network resources can not meet the demand of users when At this point we must use to control congestion management bottlenecks in the flow of resources sharing. In this paper the concept of congestion control. Congestion control of several aspects of the computer network congestion control for a rough outline.

Abstract
In recent years, with the popularity and the rapid growth of the Internet,a large number of research works have been performed to expand architecture of Internet. Among them, more and more reasonable control mechanism will undoubtedly be crucial for stable network operation. One of the most basic and important requirement is to prevent the network congestion collapse so that network operates with mild congestion and a guarantee of equity. From a point of view of demand from the users, the network must provid services for all requests of users. However, the demand of users vary largely in the initial transmission time, the demand rate and duration and are emergent in many cases. From a point of view of resources provided by the network, any network physical resources have fixed the maximum capacity. Thus, network resources will not meet the demand of users with limited resources to adapt to fluctuations in demand for large users. At this point we must use congestion management to control the share of bottlenecks for user flow. In this paper,from several aspects of the concept and method of congestion control. congestion control of computer network were outlined roughly.
Key words : network congestion, congestion control
