Abstract
In this paper, we introduce elastic optical bypasses to offload traffic bursts in Elastic Optical Networks. Firstly, the principles of the proposed mechanisms are explained. Secondly, the most spectral efficient path with the largest slices first method is proposed as a bypass-path selection policy. Various proportions of resources reserved for optical bypasses and those available for the IP layer are considered in consecutive experiments. Simulation results indicate improvements in terms of bandwidth blocking probability, the average number of hops per accepted demand, and the overall spectrum occupation in comparison to the reference approach. All the proposed mechanisms are fully compatible with the Software-Defined Networking concept.
