摘　　要：降低网络能耗和提高能量利用率的需求,使绿色IP over WDM网络成为光网络领域的研究热点。针对流量业务,以降低网络能耗和保证网络性能为优化目标,建立了分层集成辅助图模型,根据多跳疏导机制设计了IP over WDM网络光层节点优化配置下的节能多跳疏导(Optical Multiple Jump Grooming,OMJG)路由算法,进行了仿真,并与最短路径优先算法(Dijkstra)进行了比较。结果表明:在网络总能耗和业务请求阻塞率方面,设计的OMJG算法均优于传统的Dijkstra算法。The demand for decrease of network energy consumption and improvement of energy efficiency makes the green IP over WDM network a research hotspot in the area of optical communication network. For the purpose to reduce the network energy consumption and ensure the network performance for the traf- fic load, the hierarchical integrated auxiliary graph model is established, and the saving energy multiple jump grooming （OMJG）routing algorithm for the optical layer node optimization configuration of IP over WDM network designed and simulated, Simulation and comparison with the shortest path first algorithm （Dijkstra） inidcate that the OMJG algorithm is clearly superior to the traditional Dijkstra algorithm in total energy consumption and service request blocking probability of the netwok.
