摘　　要：文章在叙述了光网络中选路和波长分配(RWA)要解决的基本问题后,对有关方面的近年研究作了综述,主要包括:虚拓扑重构、业务量疏导的RWA、多播RWA、抗毁网络的RWA。抗毁问题涉及WDM网络的抗毁选路、区分可靠性、网状网的快速恢复、多故障下的抗毁。Basic problems that should be solved for routing and wavelength assignment (RWA) in optical networks are presented. After that, an overview of research achievements in recent years is presented, including virtual topology reconfiguration, RWA in traffic grooming, RWA in multicasting, and RWA in survivable networks. For network survivability, it includes survivable routing in WDM networks, differentiated reliability, fast recovery in mesh networks, and multi-link failures.
