基于可重构网络的节能方法的研究

Research on energy-saving method based on reconfigurable network architecture

针对当前IP网络的节能算法实用性不强的问题,根据可重构网络路由配置由中心服务器统一管理的架构特点,基于网络中的OSPF协议探测结果,提出了可重构网络下的节能方法。该方法首先运用改进的OSPF协议的路由算法定位出可被关闭的候选链路集合,接着应用多商品流模型重映射该集合中某些链路的流量到其他的物理路径,从而能够关闭候选链路集合中的空负荷链路实现网络的节能。通过实验模拟验证了该算法的节能效益,并给出了可重构网络中的节能算法与认可度极高的节能方法——GreenTE异同点。

With the aim to address the problem that current energy-saving algorithms in the IP network were low practical,an energy-saving method in the reconfigurable network architecture based on its natural features was proposed that the central server unified manages the routing configuration of all the routers.The method firstly using the modified OSPF protocol algorithm to determine a candidate link set in which all the links were probably closed or sleep,then the multi-commodity model was utilized to remap the traffic volume of these links to other physical paths.Thus,some links can be idle since their data flows had been redirected.It was reasonable to power off idle physical links for the purpose of saving energy.Finally,the simulated experiments had verified the effects of saving energy and the differences between the proposed algorithm and the high recognized energy-saving method –GreenTE were given.
