摘　　要：针对当前业务量疏导研究中很少涉及的QoS约束的问题,提出并研究了一种支持多优先级QoS的业务量疏导算法(Differentiated Traffic Grooming Algorithm,DTGA),该算法综合考虑了对不同等级业务QoS和网络资源利用率的优化。与目前实用的WDM光网络业务量疏导算法的性能仿真对比表明,DTGA能有效地降低高服务等级需求业务的阻塞率和节省网络资源。Due to little traffic grooming research considering QoS constraint,a kind of multi-priority QoS differentiated traffic grooming algorithm（DTGA） is proposed and studied.The different priority traffic QoS and optimized network resource utilization are taken into account comprehensively in DTGA.The comparison between DTGA and common used traffic grooming algorithms via simulation shows that DTGA can reduce the blocking probability of high priority traffic and improve the network resource utilization effectively.
