【摘要】 研究了WDM全光网中多播路由的问题,并给出一种满足时延约束的多播路由与波长分配算法,此算法是在Chlam tac[2]等人提出的波长图的基础上,将路由与波长分配统一进行,构造了时延受限低代价多播树,克服了将寻径和波长分配分步进行的弊端,具有较低的时间复杂度,避免了同类算法的较高复杂性。更多还原

【Abstract】 This article studies the question of Multicast Route in the WDM all-optical networks,and a routing and wavelength assignment in WDM all-optical networks is presented.Based on the wavelength graph that Chlamtac presents,this algorithm deals with routing and wavelength assignment as a unified process,constructs a minimal cost multicasting tree satisfying delay bound constraint.Moreover,the algorithm avoids high complexity common to most delay-constrained heuristics.更多还原
