多播格状WDM光网络中流量疏导的一种启发性算法

A Heuristic Algorithm for Grooming of Traffic in Multicast Mesh WDM Optical Networks

波分复用技术的开发应用及网络业务信息的多样化促进了多播技术的应用和发展.由于网络中波长带宽与节点间业务信息需求之间的巨大反差,使流量疏导成为必要,以节约网络资源和成本.但多播的出现使流量疏导算法变得更复杂多样.本文提出了对多播格状网络中的静态流量进行有效疏导的一种启发性算法,并取得较为优化的结果.

With the exploration and exploitation of wavelength-division multiplexing （WDM） technology, the diversification of traffics in networks has accelerated the application and development of multicast technology. Due to the big difference between wavelength bandwidth and the traffic requirement between each pair of nodes, it is necessary to groom the traffics in the network to reduce the resource usage and costs of networks. But the algorithms of traffic grooming become more complex with the appearance of multicast.This paper propeses a heuristic algorithm which grooms the static traffics in multicast mesh optical networks efficiently and achieves a good result.
