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WDM网络中的波长资源消耗,而且很大程度降低了计算复杂度。
In order to reduce the wavelength resource consumption in wavelength division multiplexing (WDM) networks, the idea of multicast routing algorithm is applied to the calculation of static service grooming and the static grooming of services is implemented by establishing a service grooming tree. In order to reduce the number of grooming trees, thereby reducing the consumption of wavelength resources in the network, the service request packets among nodes are merged, the number of service packets is minimized by using a packing algorithm, and the transmission path is shared by constructing a minimum spanning tree. The simulation results show that the proposed algorithm can effectively reduce the wavelength resource consumption in WDM networks and greatly reduce the computational complexity.
