Abstract--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.
Keywords multifiber WDM networks; layered graph; LP;
survivalbility.
