Heuristic algorithms for locating the wavelength converters in WDM network

  • 摘要: 該文首次研究了波分復用(Wavelength Division Multiplex,WDM)網(wǎng)絡中如何在最佳節(jié)點中確定波長變換器數(shù)目的算法,設計了3種啟發(fā)式算法,通過在NSFNET(the U.S.NationalScience Foundation backbone NETwork,美國科學基金會骨干網(wǎng)絡),ARPANBT(the AdvancedResearch Projects Agency NETwork,美國高級研究規(guī)劃局網(wǎng)絡),CERNET(China Educationand Research NETwork,中國教育科研網(wǎng)絡)上的仿真,比較了3種算法的性能差異,得出算法1的性能最優(yōu),且復雜度最低。另外,通過比較在部分節(jié)點以及全部節(jié)點中運用算法1確定波長變換器的數(shù)目,得出:在WDM網(wǎng)絡中,在部分節(jié)點中裝配有限的波長變換器也可以達到全部節(jié)點中裝備波長變換器的性能,并且還可以降低光交叉連接設備(Optical Cross-Connects,OXC)的成本,減少復雜的控制。
    Abstract: In this paper, three heuristic algorithms are presented about deciding how many converters are needed in the best nodes of WDM network. By simulating in NSFNET, ARPANET and CERNET, the performances of three algorithms are compared. The results show that per-formance of the Algorithm 1 is the best and its complexity is the lowest. Furthermore, by using the Algorithm 1 in the best nodes and all nodes, it is found that the- performance of wavelength converters equipped in the best nodes is not worse than that in all nodes, so the cost and complexity of OXC in the network are reduced.
