Abstract
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.
