Performance of WDM Network with Shared-Path Protection Under Self-Similar Traffic

  • 摘要: 該文利用隨機(jī)中點(diǎn)置換-分形高斯噪聲(RMD-FGN)方法生成自相似業(yè)務(wù)，并且利用分層圖方法來記錄WDM網(wǎng)絡(luò)狀態(tài)，提出了一種鏈路狀態(tài)描述模型。對(duì)自相似業(yè)務(wù)下55 Mesh_Torus共享通道保護(hù)WDM網(wǎng)絡(luò)性能進(jìn)行了仿真。結(jié)果表明：當(dāng)業(yè)務(wù)的自相似系數(shù)或方差變大時(shí)，也就是說業(yè)務(wù)的突發(fā)程度變大時(shí)，阻塞率變大，網(wǎng)絡(luò)的性能下降。增加單纖波長(zhǎng)數(shù)，可以降低阻塞率，提高網(wǎng)絡(luò)性能。
    Abstract: A method of Random Midpoint Displacement-Fractional Gaussian Noise (RMD-FGN) is applied to generate self-similar traffic. A link state model is presented and used to describe the wavelength usage of Wavelength Division Multiplexing (WDM) network with layered-graph model. The performance of a 55 Mesh_Torus WDM network with shared-path protection under self-similar traffic is simulated. The result shows that when the self-similar coefficient or the variance of traffic increases, that is, the burst of traffic rises, the block probability goes up and the performance of network decreases. The block probability falls as the number of wavelength per fiber grows.
