Abstract :
We develop integrated algorithms for dynamic provisioning of SLA-guaranteed IP services in IP-over-optical networks. By integrated, we mean that the provisioning mechanisms takes into account topology, resource, and protection information in both the IP and optical layers. This is achieved through two novel path selection algorithms developed in this paper, and through the GMPLS common control plane. The performance study shows that our proposed algorithms can really provide guarantee across multiple levels of service. In addition, we can achieve significant improvement over existing integrated provisioning approaches in terms of bandwidth utilization, request blocking probability, and algorithm complexity.
