摘　　要：在WDM网络中,业务带宽的需求远低于一个波长所提供的带宽,业务量疏导可以聚集低速业务到大容量的光路中从而有效地利用波长带宽资源.目前,大多数关于业务量疏导算法的研究没有考虑网络故障.本文综合考虑网状网生存性及业务量疏导,基于圈覆盖算法对网络进行分层,使网络结构产生分簇,提出了一种基于故障感知的业务量疏导算法,并对算法进行了仿真分析.In WDM networks, the bandwidth request of a traffic stream can be much lower than the capacity of a wavelength. Traffic grooming can aggregate low -rate connections onto high -capacity light paths to make full use of the bandwidth. But most of the algorithm related to traffic grooming has not focused on a network failure. Considering both the survivability and traffic grooming in WDM mesh networks, in this pa- per, we propose a traffic grooming algorithm based on fault - aware （FAA） and layer the network structure on basis of cycle cover algorithm. The network structure generated sub - clusters at the same time. Some simulations and analysis are also given out.
