Abstract

In the current work, we address the power-efficiency issue in a survivable elastic optical network (EON). Initially, to obtain solutions for the grooming with survivability routing and spectrum allocation problem in a software defined EON, we formulate an integer linear program (ILP) model which reduces both, the transponder numbers needed and the maximum amount of frequency slots which are occupied. Next, we propose the novel route protection with grooming and shared backup (RPwGSB) heuristic algorithm which considers four grooming cases and aims at providing adequate protection and reduced consumption of the resources (i.e., spectrum). We conduct extensive simulations to evaluate the consumed power by the optical elements which belong to the data plane. The obtained simulation results through both, the formulated ILP model and the proposed RPwGSB algorithm demonstrate a similar trend and show that with the introduction of grooming, more power savings can be obtained. Further, the results also reveal that compared to the traditional route protection with shared backup scheme which does not involve any grooming, the proposed RPwGSB algorithm achieves better performance in terms of blocking probability, total port cost and power-efficiency, simultaneously demonstrating significant spectrum savings.
