In this paper, we address the survivable routing problem with and without wavelength-continuity constraints by proposing a new Integer Linear Programming (ILP) algorithm, which is based on a simplified necessary and sufficient condition. Numerical results are given and discussed to show the efficiency of our algorithm and the impact of wavelength-continuity constraints.
