520			_aThe use of space division multiplexing (SDM) technology provides an additional level of freedom within the elastic optical networks (EONs). The SDM-based EONs (SDM-b-EONs) are envisioned to provision the enormous capacity needed by the future heterogeneous traffic. However, in SDM-b-EONs, a lightpath can span multiple spaces (i.e. cores, modes or fibres), which poses new challenges in regard to the network protection. Many studies have proposed novel protection schemes for SDM-b-EONs; however, no study has considered the grooming of traffic and the overlapping of spectrum in protected SDM-b-EONs. In this study, the OverlaPping of spEctrum and gRooming of trAffic (OPERA) method has been introduced which provides online protection to a SDM-b-EON simultaneously considering advantages obtained by grooming the traffic and overlapping the spectrum. The performance evaluation results demonstrate that OPERA (1) maintains acceptable crosstalk levels while ensuring an efficient use of the network and (2) ensures the desired transmission quality simultaneously minimizing the demands blocking.
