In this paper, we propose a network-engineering (NE) approach for improving the availability of light paths over WDM networks. By rearranging the availability of links, the average availability of light paths can be improved without sacrificing performance in terms of blocking probability and investing extra capital expenditures (CAPEX) and operational expenditures (OPEX).
