摘要
讨论了在支持波长路由的WDM网络中的路由波长分配算法。首先分析了若干种路由和波长分配方式,并给出了波长路由算法(RWA)存在的问题;然后简要地讨论了支持波长转换网络的一些特征及其存在的问题;最后根据ASON中的路由问题提出了影响路由问题的一些因素,分析了一些新算法。
This article focuses on the routing and Wavelength-Assignment (RWA) problems in wavelength-routed optical WDM networks. The authors examine the RWA problems,analyze various routing approaches and wavelength-assignment approaches proposed in the literature,briefly discusse the characteristics of wavelength-converted networks, and examines the associated research problems and challenges. Finally,the authors examine the problem of routing in ASON, give some aspects that should be considered in routing field and discuss some new routing and wavelength algorithms.
