| 摘 要： | 文章介绍目前波分复用光网络设计中的RWA问题,根据网络结构的复杂度和节点个数的多少,从静态波长路由分配法和动态波长路由分配法两种方式,探讨解决RWA问题.在静态波长路由分配法中主要针对网络中不具有波长转换和各节点的业务需求关系,将预先分配好的波长路由关系存入网络中的各节点,以解决静态RWA问题,而在动态波长路由分配法中主要针对网络中具有波长转换这一特点,根据图论中的相关理论以求得网络中波长数和路由的关系,从而解决动态RWA问题.

| Abstract: | This paper introduces the RWA problem in WDM optical Networks design and solves the RWA problem from the static-routing and wavelength algorithm and dynamic-routing and wavelength algorithm which according to the complexity of Networks and the number of node.In the static routing and wavelength algorithm,we design the relation of wavelength routing and store the net-node in accord to the business requirement and no-wavelength-switching in network and solve the static RWA problem.In the dynamic-routing and wavelength algorithm,we get the relation of wavelength and routing by theoretical analysis in accord ance to the wavelength-switching in network,so we can solve the dynamic RWA problem. |
