摘　　要：针对IP over WDM网络,提出一种面向多优先级的绿色路由算法,对网络传送的业务进行QoS等级划分。对不同优先级的业务,制定不同的路由选择标准,综合考虑业务的QoS要求和网络功耗优化问题。仿真结果表明,与普通绿色路由算法相比,该算法在低负载时可以减少约40%的时延和52%的物理跳数,同时节能效果也优于普通绿色路由算法。A multi-priority green routing algorithm which divides traffics into different classes based on their QoS requirements is put forward for IP over WDM network. This algorithm sets different routing standards for different classes, taking traffics＇ QoS requirements and the optimization of the network power consumption in- to account comprehensively. The result of simulation shows that compared with ordinary green routing algo- rithm, this algorithm can reduce about 40% delays and 52% traffic transportation hops under low traffics; meanwhile its energy-saving effect is more considerable than ordinary green routing algorithm.
