Flexible-grid elastic optical networks (EONs) have attracted intensive research interests for
the agile spectrum management in the optical layer. Meanwhile, due to the relatively small …

Spectrum fragmentation limits the efficiency of spectrum utilization in elastic optical networks
(EONs). This paper studies how to take advantage of the centralized network control and …

Elastic optical networks employ flexible routing and spectrum allocation algorithms to
support diverse services and heterogeneous traffic. By splitting a traffic request into multiple …

Routing and Spectrum Assignment is a key issue in Elastic Optical Networks (EON). Under
dynamic traffic conditions, spectrum fragmentation of the frequency resources reduces the …

Abstract In Elastic Optical Network (EON), spectrum fragmentation refers to the existence of
non-aligned, small-sized blocks of free subcarrier slots in the optical spectrum. Several …

Abstract A novel Class-Based First Fit (CBFF) spectrum allocation policy is proposed for
dynamic flexgrid optical networks. The effectiveness of the proposed CBFF policy is …

While elastic optical network technologies have emerged as promising solutions for future
ultra‐high‐speed optical transmission, the unavoidable spectral fragmentation problem that …
