摘要: 由于成本及技術(shù)的原因, WDM光網(wǎng)絡(luò)中的波長變換設(shè)備資源和單纖波長數(shù)有限,但在網(wǎng)絡(luò) 建設(shè)時,會預(yù)留富裕的光纖,如何依據(jù)動態(tài)業(yè)務(wù)有效利用這些光纖降低網(wǎng)絡(luò)阻塞率,并優(yōu)化單纖波長配置以 滿足網(wǎng)絡(luò)性能,具有現(xiàn)實意義。該文提出了一種WDM網(wǎng)絡(luò)的稀疏多纖及波長配置算法,該算法基于動態(tài) 業(yè)務(wù)。仿真結(jié)果表明,利用稀疏多纖的網(wǎng)絡(luò)配置,只需要較少的單纖波長即可滿足網(wǎng)絡(luò)阻塞性能要求。

Abstract: Constrained by the price and technology, not only the wavelength converters laid in WDM network but also the Wavelength Per Fiber (WPF) is limited. But there are usually some spare fibers in links, so it is important to make full use of these fibers to lower the blocking probability in WDM networks. This paper proposes a sparse multifiber and wavelength assignment algorithm based on dynamic traffic service WDM-networks. The simulation results show that by assigning sparse multifiber, the blocking performance can be obtained with fewer number of WPF. -
