一种基于休眠的IP over WDM网络多策略节能算法

Multi-strategy energy-saving algorithm based on sleeping in IP over WDM networks

针对IP over WDM网络的节能目标,提出了一种基于休眠的多策略网络节能算法,根据IP层与WDM层、网络节点与链路的不同属性,结合IP层与WDM层制定不同的休眠方式,使网络设备在非高峰时段能根据实际业务连接请求情况有选择地进入低能耗休眠或待机状态,达到实现节能目的。

In order to reach the goal of saving energy of IP over WDM network, a new multi-strategy ener- gy-saving algorithm based on sleeping mechanism is proposed, which defines different sleep method regard- ing different properties of IP layer and WDM layer as well as network nodes and links, so network equipment can be turned into low-power sleep mode according to practical traffic situation, and leads to energy-saving.
