摘　　要：利用分类可靠性概念解决WDM多纤双向环网中的路由和波长分配问题。基于分类可靠性概念和环网的重用保护波长机制 ,提出了一种改进的最难重用优先算法。利用该算法 ,可以在满足每个连接可靠性要求的同时 ,使整个环网所需的波长里程数最小。The concept of differentiated reliability(DiR) was applied to solve the routing and wavelength assignment problem in multiple-fiber bidirectional WDM(Wavelength Division Multiplexing) rings.Based on the DiR concept and the mechanism of reusing protection wavelength in rings, an improved Difficult-Reuse-First algorithm was proposed. This algorithm can minimize the ring total wavelength mileage, while guaranteeing the required reliability degree of each connection.
