Conclusions l l In this paper, the author have studied the optimal configuration of p-cycles in survivable WDM optical mesh networks with sparse wavelength conversion while 100% restorability is guaranteed against any single failures. The author formulate the problem as an integer linear program.

Conclusions l l The objective is to minimize the cost of link capacity used by all p-cycles to accommodate a set of traffic demands. In the proposed p-cycle configuration architecture, the author take converter sharing into account which enables the network to require as few converters as possible to attain a satisfactory level of performance.
