| 摘 要： | 针对IP over WDM网络,基于多跳光旁路和流量疏导,以减少能耗为目标对网络链路配置进行设计;考虑多跳光旁路会增大业务传输距离的问题,分析了光路建立顺序对业务传输距离的影响;通过优先路由短距离业务和限制最大传输跳数来减少业务的平均传输跳数。仿真结果表明,优先建立短距离光路的启发式算法与Dijkstra算法相比可以减少25%～55%的能耗,业务平均物理跳数与Dijkstra算法相差在1跳之内。

| Abstract: | Based on multi-hop bypass and traffic grooming,link configuration for IP over WDM network is designed aiming at reducing energy consumption.On the problem that multi-hop bypass may result in longer transportation distance,the interrelationship between sequence of light-paths setting up and traffic traversing lengths is analyzed.Shortest distance demand first routing and constraint on transportation distance are adopted to reduce average transportation hops.Simulation results show short distance first heuristics,compared with Dijkstra algorithm,can reduce the energy consumption by 25%~55%,and the extra average traffic transportation hops is less than 1. |
