Distributed Holding-Time-Aware shared-path-protection provisioning framework for optical networks

Abstract

New applications are likely to ask for a more flexible bandwidth, large bandwidth for limited amount of time. In order to meet these new requirements, flexible optical transport networks in which connections could be set up and released on dynamic short-term basis have to be introduced. We propose a distributed Holding-Time-Aware provisioning framework based on intelligent destination routing to assign and manage the working and the protection paths as well as their wavelength(s) of each connection. In our framework, we propose to utilize knowledge of connection holding time to provide efficient provisioning of shared-path-protected connections in survivable optical mesh networks. We show through a simulation study that the performance of the proposed holding-time-aware compared to a holding-time-unaware is significant.
