Executive Summary

This paper addresses multi-domain light-path provisioning within the context of correlated multi-failure events. The paper jointly incorporates both risk minimization and traffic engineering objectives, and develops a novel graph theoretic scheme for distributed operation in realistic optical network settings. Detailed performance evaluation results are then presented to gauge the effectiveness of the proposed multi-domain provisioning solution. Optical Dense Wavelength Division Multiplexing (DWDM) networks have matured rapidly in the last decade and now offer unprecedented bandwidth scalabilities.
