Design of P-Cycles Under a Wavelength Continuity Assumption

Executive Summary

While there are many studies on the efficient design of p-cycles which advertise their spare capacity efficiency, few of them consider such a design under the wavelength continuity assumption, i.e., no wavelength converter at any node. In this paper, the authors propose to investigate thoroughly the issue of wavelength conversion vs. wavelength continuity for pcycles, with large scale optimization tools in order to get an exact estimate of the consequences of the wavelength continuity assumption on the spare capacity requirements and on the provisioning cost. Differences with previous work are that they consider exact efficient scalable models instead of heuristics, as well as joint optimization of routing and protection schemes.
