PtrNet-RSA: A Pointer Network-Based QoT-Aware Routing and Spectrum Assignment Scheme in Elastic Optical Networks

Journal of Lightwave Technology
To enable flexible service provisioning in elastic optical networks (EONs), quality of transmission (QoT) estimation and dynamic routing and spectrum assignment (RSA) are critical network management tasks.

On the Complexity of Routing and Spectrum Assignment in Flexible-Grid Ring Networks [Invited]

Journal of Optical Communications and Networking, 2014
The adoption of a flexible grid will benefit the network design and control plane of future optical networks by providing increased adaptability of spectral resources to heterogeneous network conditions. Unfortunately, this flexibility is gained at the cost of significant additional complexity in the network design and control.

Systematic Literature Review of the Use of Computational Intelligence in the Routing and Spectrum Assignment Problem in Elastic Optical Networks

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
Elastic optical networks (EONs) have characteristics that meet the growing demand for current and future bandwidth, such as 5G and Internet of Things. In EONs, connections must have a route and a spectrum slice available between the nodes to establish ...

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.
