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。
