Abstract
This paper proposes a survivable virtual network embedding model over elastic optical network with considering the shared protection against any single substrate node or link failure. We consider the backup computing and bandwidth resource sharing to reduce the required backup resources. A heuristic algorithm with polynomial time complexity is presented to solve the problem with considering promoting the backup resource sharing. The results observe that the rejection ratio is reduced about 60% in average by introducing the shared protection compared to the dedicated protection in our examined scenarios.
