Abstract
This paper evaluates the performance of a new scheme for the differentiated-resilience provisioning of lightpaths in a wavelength-routed optical network. A novel differentiated-resilience optical-services model (DROSM) is proposed to enhance the performance of the optical network. First, an analysis of optical-resilience options is presented. Then, a classification of optical services according to their resilience requirement is proposed with respective resilience options. In particular, a novel link-management mechanism is proposed to assist the routing and wavelength allocation. Our numerical results show that differentiated-resilience provisioning has significant merit over that of single resilience provisioning in the optical network.
