In this paper, the authors discuss about node and link protection in wavelength division multiplexing mesh networks to assure 100% node protection in addition to the protection against the single link failure and also dual link failures, for this purpose, they propose a p-cycle protection scheme. Previous studies offer some node protection shows the expense of some overlapping p-cycle with very mild impact on the bandwidth efficiency, they can guarantee node protection. A design model and solution method is introduced for solving based on the large scale optimization tools namely Column Generation (CG).
