Cross-Layer Adaptive Elastic Optical Networks

Journal of Optical Communications and Networking, 2018
Optical networks are designed to be operated statically: lightpaths are provisioned for uninterrupted operation for several years using high margins to anticipate the deterioration of their quality of transmission (QoT) from various factors (equipment aging, malfunctioning, and maintenance operations).

Application of Machine Learning in Elastic Optical Networks

2018 European Conference on Optical Communication (ECOC), 2018
Machine learning (ML) techniques have been adopted in elastic optical networks to enable automated operations and extract more capacity from the physical layer. We review and discuss various applications of ML in link monitoring, link modeling, link provisioning and network control.

QoT Aware Adaptive Elastic Optical Networks

Optical Fiber Communication Conference, 2017
Operating Elastic Optical Networks with low margins increases their efficiency but suffers from soft-failures, rendering the QoT of lightpaths unacceptable. We present a toolkit that leverages the flexibility dimensions to survive against QoT problems.

Spectrum Fragmentation Management in Elastic Optical Networks

2019 21st International Conference on Transparent Optical Networks (ICTON), 2019
In elastic optical networks (EONs), bandwidth fragmentation is a challenging issue, which need to be suppressed to improve the traffic admissibility. In EONs, lightpaths are established and released dynamically, which cause bandwidth fragmentation that occurs when unoccupied isolated slots are not aligned along the route and contiguous in the spectrum.

Elastic optical networks: The vision of the ICT project IDEALIST.

2013
The current generation of optical networks based on a fixed wavelength grid and on fixed-rate transponders would impose relevant limitations for future transmission rates exceeding 100 Gb/s, thereby limiting the number of potential implementations and making a new generation of elastic optical networks (EON) necessary.
