Analytical Modeling of Switching Fabrics of Elastic Optical Networks
IEEE Access, 2020 This article proposes an analytical method for determining the traffic characteristics of multi-service switching networks in elastic optical networks. The method takes into consideration the limitations of W-S-W (wavelength-space-wavelength) switching ...

Channel-Based RSA Approaches for QoS Protection of Slices Over Elastic Optical Networks
IEEE Access, 2022 Resource efficiency and survivability are critical concerns in elastic optical networks (EONs) with virtualization. In this paper, we investigate some important aspects in network survivability design against single-link failure under dedicated ...

Optical Grooming in OFDM-Based Elastic Optical Networks [PDF]
Optical Fiber Communication Conference, 2012 We propose a novel optical grooming approach to aggregate and distribute traffic directly at the optical level in OFDM-based elastic optical networks. Significant transmitter and spectrum saving is achieved compared to non-grooming scenario.

On the Filter Narrowing Issues in Elastic Optical Networks [PDF]
Journal of Optical Communications and Networking, 2016 This paper describes the problematic filter narrowing effect in the context of next-generation elastic optical networks. First, three possible scenarios are introduced: the transition from an actual fixed-grid to a flexi-grid network, the generic full flexi-grid network, and a proposal for a filterless optical network.

Design of Optical Wireless Networks with Fair Traffic Flows
Journal of Applied Mathematics, 2014 The paper presents a method for optimising the wireless optical network that carries elastic packet traffic. The particular focus is on modelling the effect of elastic traffic flows slowing down in response to the decrease of the optical transmission ...

Heuristic Chaotic Hurricane-Aided Efficient Power Assignment for Elastic Optical Network
IEEE Access, 2020 In this paper, we propose a dynamical power allocation (PA) procedure for elastic optical networks (EONs) based on the evolutionary hurricane search optimization (HSO) algorithm with a chaotic logistic map diversification strategy with the purpose of ...
