The derivation of the integer linear programming formulas and the relaxed heuristic algorithm, to restore paths in WDM networks with wavelength converters, was presented. The heuristic algorithm was proposed as a suboptimum solution for fast on-line restoration, as it allows sharing spare capacity among several link faults, thereby improving the network resource efficiency and flexibility. The results showed that the proposed heuristic algorithm had a better performance in terms of recovery cost, additive latency and restoration coverage, when compared with the disjoint path protection and the shared path protections.
