We develop a new analytical model for the estimation of blocking probabilities in OPS and OBS networks. The model is used to analyze the performance of a new deflection method that uses multiple wavelength channel reservation thresholds, and gives network designers greater control over the performance of the network. The accuracy of the analytical model is assessed using simulations. © 2006 IEEE.
