Internet上随着网络的不断发展和用户的要求越来越高,以为用户提供更高服务质量(Quality of Service,QoS)为目标的研究越来越重要。而强壮的网络拥塞控制是保障用户服务质量的基础。“随机早期检测算法”(Random Early Detection,RED)[1],由于其在实际应用的广泛,成为研究热点。文章首先探讨远端流和近端流在在传输过程中的不公平性和链路资源利用情况,在此基础上提出路由器将网络中的流分为远近两种区分对待,改进RED算法以提高链路资源的利用率和流在传输过程中的公平性。
With the continuous development of the Internet and the increasing demands of users on the Internet, it is more and more important to study the goal of providing users with higher quality of service (QoS). The strong network congestion control is to protect the quality of service users based. Random Early Detection (RED) [1] has become a research hotspot due to its wide range of applications. Firstly, the paper discusses the unfairness of the remote and near-end flows in the transmission process and the utilization of the link resources. Based on this, it is proposed that the router classifies the flows in the network into two kinds: far and near, and improves the RED algorithm Link resource utilization and flow in the transmission process of fairness.
