计算机网络拥塞的高效控制方法研究

Computer Network Congestion Control Method of High Efficiency

研究计算机网络的拥塞问题,由于网络拥塞,造成数据包丢失、资源分配效率低,使网络服务质量(Qos)低。针对计算机网络中传输的报文过多出现拥塞时,传统的TCP拥塞控制机制只是模仿交通指挥的原则,对网络拥塞实行正常控制机制处理,不能保证网络服务质量的问题。为了高效解决网络拥塞的问题,提出了一种改进的拥塞控制方法。以传输控制层的网络拥塞控制机制为基础,结合网络层的网络资源队列管理策略共同解决网络拥塞问题。仿真结果表明,这种改进的方法不仅及时解决了网络拥塞的问题,而且保证了计算机网络通信的服务质量,是一种高效地控制网络拥塞问题的方法,为网络性能优化设计提供了依据。

Research the computer network congestion problem. As the network congestion, causing packet loss and low efficiency of resource allocation, and resulting the network low quality of service （Qos）. When transmission message appear too much congestion in a computer network, the traditional TCP congestion control mechanism only imitate traffic control principle, to implement a normal network congestion control mechanism processing, can＇t guar- antee that the network service quality issues. In order to solve the problem of efficient network congestion, this paper put forward an improved congestion control method. To transfer control and the layer of network congestion control mechanism for the foundation, combined with the network layer of network resources queue management strategy to address common network congestion problem. The simulation result indicates that the improved method not only timely solve the network congestion problem, and ensure the computer network communication service quality. This method is a kind of efficient methods to control network congestion problem and provide the basis for network performance op-timization design.
