Optical WDM networks, blocking probability model by Barry and Humblet and model by Al-Zahrani et al., new blocking probability model for limited wavelength conversion
Optical WDM networks are providing the huge bandwidth and they are still very attractive in backbone networks. In this paper we study the blocking probability model by Barry and Humblet for single fiber WDM networks and model by Al-Zahrani et al. for multifiber WDM networks. The model by Barry and Humblet is proposed for no and full wavelength conversion and we extend this model for limited wavelength conversion. In fact, the proposed model is generalized for no, limited and full wavelength conversion. The results of these models are compared for single fiber and multifiber networks. Due to the results, taking into account the wavelength utilization and the blocking probability the optimal network could be designed with respect to costs of components.
