Performance of WDM Network with Shared-Path Protection Under Self-Similar Traffic
自相似业务下共享通道保护WDM网络性能分析

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 5×5 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.
