摘　　要：基于Fat-tree拓扑的数据中心网络中存在一系列保证通信可靠性的富连接。这些富连接导致网络低负载情况下有大量设备处于空闲状态,而传统网络无法在保证网络可靠性的同时对设备进行调度。为解决该问题,设计ESPP:基于软件定义网络SDN(Software Defined Network)的节能路径规划系统。客户端通过控制器收集网络信息,计算节能路径,调节数据流向,调度物理设备。在Mininet搭建的模拟网络环境中进行测试的结果表明,该系统能够实时计算节能路径,下发节能策略,有效降低能量消耗,实现数据中心网络的绿色节能。In the data center network based on Fat-tree topology,reliable communication is often realized by a series of rich connections,which cause that a large number of devices keep idle when the traffic load of the network is low.However,the traditional network cannot guarantee the network reliability while scheduling the devices.To solve this problem,we designed ESPP,an energy-saving path planning system based on SDN(Software Defined Network).In this system,the client collected the network information,calculated the energy-saving path,adjusted the data flow and scheduled the physical devices by the controller.Through the test in the virtual network environment set up by Mininet,the results show that the system can calculate the energy-saving path in real time,send energy-saving strategies,efficiently decrease the energy consumption,and achieve energy-saving in data center networks.
