Global Resources Integrated Resilience for Software Defined Data Center Interconnection Based on IP Over Elastic Optical Network

We propose a novel global resources integrated resilience (GRIR) algorithm for a software defined data center interconnection architecture based on IP over elastic optical network (EON). The proposed algorithm provides resilience using the multiple stratums resources and enhances the data center service resilience responsiveness to the dynamic end-to-end recovery demands in case of the converged optical node failure. Our simulation results indicate that GRIR achieves significant improvements in terms of path blocking probability, resilience latency and resource occupation rate, compared with other resilience algorithms.
