摘　　要：本文讨论了当今计算机网络中的服务质量控制的有效方法。计算机网络发展至今,已经由传统的纯数据业务转向了兼有语音、图像、视频的多媒体网络业务,而传统的网络是提供尽力而为的服务,无法保证服务质量,这就使网络的拥塞问题日趋严重。解决网络拥塞的途径有许多,可以提高网络本身的带宽,可以减少或限制某些业务流量,可以改善网络节点路由器的处理性能。由此可见,网络服务质量（QoS）控制既是一个急待解决的问题,又是一项综合性的系统工作。The paper＇s main work is discussing some effective methods of solving the problem of QoS.The problem that the paper wants to solve is QoS controlling.With the development of computer network,more and more voice、 picture and video transmit through network instead of single data.Only best effort service is provided by traditional network,so that the congestion problem becomes serious.There are lots of methods to slove the network congestion,for example,widening network bandwith,restricting or deducing some operation flow,improving the performance of router.In summary,solving the problem of QoS is ont only an urgent task,bat also a complicated and big work.
