摘　　要：提出一种高效的集中式数据中心网络路由(Efficient Centralized Data Center network Routing,ECDCR)策略。ECDCR使用集中控制器收集和发送网络链路状态,并将实际的路由计算卸载到每个交换机上。根据数据中心网络的固定模式,交换机的路由计算简化为表查找方式,即将链路状态变化与预先安装的基本拓扑进行比较,并根据预定义规则更新路由路径。采用虚拟机和物理交换机进行大量实验,结果表明,与现有路由策略相比,ECDCR展现出了更优秀的性能。This paper proposes an Efficient Centralized Data Center Network Routing Strategy(ECDCR).ECDCR uses a centralized controller to collect and send network link status and offload the actual routing calculation to each switch.According to the fixed mode of the data center network,the routing calculation of the switch is simplified to the table lookup method,that is,the link state change is compared with the pre-installed basic topology,and the routing path is updated according to predefined rules.This paper uses virtual machines and physical switches to carry out a large number of experiments.The results show that ECDCR shows better performance compared with the existing routing strategies.
