摘要 针对波分复用光网络中的业务疏导问题,文章基于通道组交换网络模型,采用波分复用网络中的相对容量算法来解决业务疏导的路由、波长分配和时隙分配问题。基于该模型的算法能够将波长和时隙分配这两个通常分开解决的问题一步解决,因此比现有方法具有更好的效能,仿真也验证了这一点。 In view of the traffic grooming issues in WDM networks,the Relative Capacity Influence(RCI) algorithm is used to deal with such issues as Routing,Wavelength and Time-slot Assignment(RWTA) in WDM networks on the basis of a trunk-switched network model.By using this algorithm,the wavelength and time slot assignment issues that are usually dealt with separately can be solved simultaneously.The simulation results prove that the algorithm performs better than the existing ones when these issues are dealt with separately.
