A heuristic method for design of survivable WDM networks with p-cycles

We consider a new heuristic method for design of survivable wavelength-division multiplexing (WDM) networks with preconfigured protection cycles (p-cycles). Numerical studies show that the new heuristic works well for different traffic patterns, and the spare capacity obtained by the new heuristic is very close to that of the optimal solution but with much reduced computational time.
