摘　　要：　流量疏导是当今光网络研究中一个学术与商业价值并重的研究热点。在WDM(波分复用)光网络中使用流量疏导技术不仅能够有效地降低网络成本,也能够使网络性能得到必要的优化。为了适应当前网络中普遍存在的突发多变的业务分布,引入了一种称为网络可重构动态流量疏导的新型流量疏导概念,并对疏导进行了分类,较全面地论述和评价了近年来这方面的研究,最后对今后的研究作了一番展望。Traffic grooming is one of the hot topics having both high scientific and commercial values in the research of optical networks. Efficient grooming of traffic can not only effectively reduce the network cost, but also optimize the network performances. To deal with the burst and changing traffic in current networks, a new concept of traffic grooming, named as reconfigurable grooming under dynamic traffic, is proposed. We also classified this new grooming type, provided a thorough review of the research in this area, and finally forecasted the future research directions.
