摘要: 針對容量有限的透明IP over WDM網(wǎng)絡(luò)模型，該文提出一種基于路徑的整數(shù)線性規(guī)劃(ILP)方法來優(yōu)化網(wǎng)絡(luò)的能耗。相對基于連接的整數(shù)線性規(guī)劃方法，該方法可以在光層提供更多的路徑選擇組合。仿真結(jié)果顯示，基于路徑的整數(shù)線性規(guī)劃方法能夠通過選擇更優(yōu)的光路組合進一步降低網(wǎng)絡(luò)的能耗。

Abstract: A path based Integer Linear Programming (ILP) method is proposed to optimize the network energy consumption under the bandwidth constrained transparent IP over WDM network model. Compared with the link based ILP method, this method can provide more lightpath combinations in the optical layer. The simulation results show that the path based ILP method can select the better lightpath combinations than the link based ILP method, and achieve lower network energy consumption. -
