This article proposes a survivability evaluation model for multifiber WDM networks, in which the extended layered graph is developed to jointly optimize the wavelength routing and wavelength assignment problems, and three different edge cost functions are evaluated in terms of traffic engineering. Linear programming (LP) equations are formulated to optimally determine the working lightpath and the corresponding protection lightpath under the schemes of shared protection and dedicated protection. The extensive simulations show that shared protection with the fiber and wavelength-based cost function provides the best survivability.
