多約束條件下WDM光網(wǎng)中多播選路和波長分配算法

An Algorithm of Multicast Routing and Wavelength Assignment with Multiple Constraints in WDM Optical Networks

  • 摘要: 在光層構(gòu)建多播選路和波長分配時，必須考慮一些約束條件。主要的約束條件有以下4種：稀疏分光器配置約束、波長連續(xù)性約束、能量損傷約束及稀疏波長轉(zhuǎn)換器約束。目前，研究人員只是針對其中一個或兩個約束條件進(jìn)行了算法研究。該文在詳細(xì)分析各種約束條件之后，提出了一種基于多約束條件下多播選路和波長分配啟發(fā)式算法。最后在CERNET和NSFNET兩種網(wǎng)絡(luò)拓?fù)渖线M(jìn)行了仿真實驗。根據(jù)算法仿真結(jié)果可以得出該算法可以有效地解決多約束條件下的多播路由及波長分配問題。
    Abstract: At the network layer, several constraints must be taken into account when calculating multicast routing and wavelength assignment. The constraints mainly include the following four aspects: sparse light splitter constraints, wavelength continuity constraints in WDM optical network, power budget constraints and sparse wavelength convert constraints. So far, most papers analyzed only one or two of these constraints respectively. This paper illuminates these constraints in detail first and then brings forward a heuristic algorithm with multiple constraints. Finally, designs two simulations on CERNET and NSFNET network topology. The results of the two simulations indicate the validity and feasibility of the algorithm.
