AbstractIn this article, we focus on the optimization of lightpath routing in an online Space Division Multiplexing-based Elastic Optical Network (SDM-b-EON) which is protected by the dedicated route protection (DRP) strategy. In view of the aforementioned, the Online Protection and Routing Algorithm with Regeneration (OPaRAwR) method is proposed which (i) protects the lightpaths through DRP, (ii) accounts for the presence of transceivers in the network, and (iii) ensures the routing of translucent lightpaths through the spectral super-channels over the spatial modes links. In regard to regeneration, we investigate two scenarios which differ in their regeneration variability level in addition to the adjustment of modulation formats (MFs) as per the transmission route characteristics. Extensive simulation experiments are conducted considering realistic transmission reach values and two realistic network topologies. The obtained simulation results demonstrate that the proposed OPaRAwR method significantly outperforms various reference techniques in terms of bandwidth blocking probability (BwBP). In addition, the results also show that significant benefits can be obtained in regard to the utilization of resources (spectrum and transceivers) with much lesser BwBP when the regeneration is conducted with complete flexibility and MF conversion is also permitted at every node of the SDM-b-EON.

AbstractIn the current work, we focus on the optimization of lightpath routing in a Space Division Multiplexing based Elastic Optical Network (SDM-b-EON) for which we propose an online routing algorithm, named as Resource Efficient Online Routing Algorithm with Regeneration (REORAwR) which, in addition to ensuring the routing of translucent lightpaths through spectral super-channels over spatial modes links also accounts for the presence of the transceivers in the network. The proposed REORAwR algorithm is tunable such that it can either aim to reduce the bandwidth blocking probability or can aim to minimize the overall consumed power. In regard to regeneration, we investigate two scenarios which differ in their regeneration variability level in addition to the adjustment of modulation formats as per the transmission route characteristics. We conduct extensive simulations considering two realistic network topologies and realistic transmission reach values. The obtained results demonstrate that significant benefits can be obtained in regard to the utilization of both the major network resources (spectrum and transceivers) when regeneration is conducted with complete flexibility and modulation format conversion is also permitted at every node of the SDM-b-EON. In addition, the obtained results also show that when compared to spectrum usage, in terms of the overall consumed power, the performance profits which can be obtained in a translucent SDM-b-EON are very small.
