Abstract

As optical network deployments increase, multidomain survivability is becoming major concern. To address this issue, in this paper we propose a novel graph partitioning technique for improved protection scalability in such networks. To demonstrate the efficiency of our method, we also extend the p-cycle concept to expanded multi-domain settings. Overall simulation results show the efficiency of our proposed solution in terms of resource utilization and running time.
