Abstract

This paper investigates the use of restoration for desaster recovery in Elastic Optical Networks (EONs). The proposed algorithms consider different requirements on bandwidth degradation and restoration delay while restoring conections in a gradual and non-gradual way. The main contribution of the proposed approachs is allow a better adaptation of connection recover process to the post-disaster network conditions and consequently, increase the number of restored connections. To assess the performance of the proposed algorithms, comparisons with an approach of literature are performed. Results show improvement on restoration of connections and reduction of blocking rate, which highlights the benefits of the proposed algorithms.
