Efficient Design and Management of Reliable Optical Networks

Given the cost of physically modifying the backbone, as well as the relatively slow speed at which core architectures change compared to higher layers, it is important to be able to optimize the network using soft solutions to achieve better performance. A few important aspects of network reliability and failure management are studied in this thesis. First, a study on the impact of multiple failures and techniques for addressing such failures are presented. Second, service differentiation based on reliability needs is studied. Service differentiation is critical in balancing network operation costs as well as in maximizing network utilization. Third, a cost-efficient, high-speed recovery scheme is introduced and evaluated under online non-dynamic and dynamic scenarios, as well as static provisioning applicable to protecting mission-critical traffic. Finally, the impact of physical layer impairments on network reliability is presented.
