摘要
随着多播消息流在航空电子全光波分复用网络中的普遍应用,多播路由问题被广泛研究,合理的多播路由配置能够在充分利用网络资源的同时,提高网络通信效率。对全光航空电子WDM网络进行了模型抽象,并针对包含与不包含波长转换器的网络,分别提出以最小化网络总费用为目标的线性规划算法。将其用于NSFNet网络拓扑进行多播路由配置,配置结果显示,算法在保证网络实时性的前提下减少了网络的总费用。
Abstract
With the application of the multicasting information flow in the avionics all-optical Wavelength Division Multiplexing (WDM) network, the multicast routing problem was investigated more and more widely.The proper configuration of multicast router can not only make full use of the network resource, but also improve the communication efficiency of networks.In this paper, a model of avionics all-optical WDM network is built up and the integer linear programming algorithms with the objective of minimum total cost are proposed separately for network schemes with and without wavelength converter.The algorithms are used in NSFNet network topology for multicast routing configuration.The simulation results show that the algorithm can minimize the cost and ensure the real-time capability.
