Abstract
The integer linear programming formulas are derived and the relaxed heuristic algorithm is proposed to restore paths in WDM networks with wavelength converters. Compared with the disjoint path protection and the shared path protection methods, the proposed heuristic algorithm has much better performance in terms of recovery cost, additive latency, and restoration coverage
