Optimal spectrum granularity for spectrally-efficient elastic optical networks [PDF]

Scientific Reports
In this paper, we compute the optimal slot width which provides a good trade-off between the blocking probability and network cost, aiming to achieve a spectrally and cost-efficient solution for Elastic Optical Networks (EONs).

Hybrid Routing and Spectrum Allocation in Elastic Optical Networks by Machine Learning and Topological Metrics

Optics
To meet the increasing demands for data, elastic optical networks (EONs) require highly efficient resource management. While classical Routing and Spectrum Assignment (RSA) algorithms establish a path and allocate spectrum, advanced versions such as ...

Temporal and Spectral 2D Fragmentation-Aware RMSA Algorithm for Advance Reservation Requests in EONs

IEEE Access, 2021
In this paper, we explore the problem of routing, modulation and spectrum assignment (RMSA) for advance reservation (AR) requests in elastic optical networks (EONs), with the objective to further reduce the blocking probability and improve the spectrum ...

LBFA: A Load-Balanced and Fragmentation-Aware Resource Allocation Algorithm in Space-Division Multiplexing Elastic Optical Networks

Photonics, 2021
We consider a space-division multiplexing elastic optical network (SDM-EON) that supports super-channels (SChs). A Sch comprises a set of contiguous frequency slots on multiple cores in a multi-core fiber.
