摘要
拥塞控制是网络技术中一个非常重要的问题,研究区分服务(DiffServ)网络的拥塞控制具有重要的实际意义。本文提出了一个面向DiffServ网络的拥塞控制方案,其基本思想是在DiffServ网络中设立拥塞控制中心,负责检测网络的运行状态,在发生拥塞时发出控制指令以缓解拥塞。本方案应用模糊控制技术,并结合速率控制在入口边界节点上限制数据流的速率,以达到控制拥塞的目的。
A Dynamic congestion control scheme for the DiffServ network is presented in this paper. Its basic idea is to set up a congestion control center for the DiffServ network, which will detect the running status of the network, and provide control instructions if necessary. Fuzzy control technology is applied when congestion control center is performing control decisions. And rate-based control policy is adopted on the network edge.
