WDM网络逻辑拓扑重构的一种方法

A Method for Reconfiguring Logical Topologies in WDM Networks

针对网络业务流量的动态变化,为保证网络具有良好传输性能,需对逻辑拓扑进行重构.提出了一种基于最小化网络光路变化数量准则的逻辑拓扑重构方法,给出了问题的ILP(IntegerLinearProgramming)描述,进行了数值仿真验证,结果显示该算法正确、有效.

Logical topology should be reconfigured to guarantee the networks have a good transmission performance with dynamic traffic. In this paper, we present a logical topology reconfiguration scheme in terms of the rule of minimizing network lightpath changing quantity, and describe the ILP algorithm in detail. The simulation results show that the algorithm is correct and effective.
