摘　　要：从下一代光网络的业务需求出发,研究了在自动交换光网络(ASON)架构下面向业务的路由与波长分配(RWA)问题,提出了适应光网络向业务网络演进环境下面向业务的RWA概念,并分别就选路和波长分配问题进行了初步的探讨;面向业务的网络环境要求能为业务提供区分服务,以提供区分服务为目的对基于优先级的RWA算法进行了研究,并提出了面向区分业务的RWA实现框图。In view of the service requirements of the next generation optical networks, we study some service oriented Routing and Wavelength Assignment （RWA） issues in ASON infrastructure and present the concept of service-oriented RWA in conformity with the evolution of optical networks to service networks and make preliminary investigations in routing and wavelength assignment respectively. In the service oriented network environment, it is necessary to offer differentiated services and study the priority-based RWA algorithm in order to achieve this aim and present the block diagram for the implementation of differentiated services-oriented RWA.
