| 摘 要： | 为了减少波分复用(WDM)网络中波长资源消耗,将组播路由算法的思想运用于静态业务疏导的计算,通过建立业务疏导树来实现静态业务疏导.为了减少疏导树的数量,从而减少网络中波长资源的消耗,将节点间的业务请求分组归并,利用装包算法使业务分组的数量最少,并通过构建最小生成树实现传输路径共享.仿真结果表明,本文的算法可以有效地减少...

| Abstract: | For saving the source of wavelength in WDM networks,the multicast routing is used in the static traffic grooming algorithm.The traffic grooming trees are constructed for the implement of traffic grooming,and the grooming trees are minimized to decrease the consumption of wavelength.So the traffic between the network nodes is grouped,and the packing algorithm is used for reducing the group numbers.In order to realize the path sharing after traffic packing,the minimum spanning tree is constructed.... |
