On the worthiness of flexible grid in elastic optical networks
2015 European Conference on Optical Communication (ECOC), 2015Elastic networks are agreed as the right solution to improve optical networks performance. This work discusses about flexible grid usage value, supported by extensive simulations. Elastic connections using fixed grid spectrum allocation can actually lead to better network performance.

QoT Aware Adaptive Elastic Optical Networks
Optical Fiber Communication Conference, 2017Operating 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.

Energy efficiency in elastic-bandwidth optical networks
2011 International Conference on the Network of the Future, 2011The forecasted growth in the Internet traffic has made the operators and industry to be concerned about the power consumption of the networks, and to become interested in alternatives to plan and operate the networks in a more energy efficient manner. The introduction of OFDM, and its property of elastic bandwidth allocation, opens new horizons in the ...

Toward Deeply Virtualized Elastic Optical Networks
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013We discuss the virtualization in optical networks from the elastic networking level to sliceable equipment level. We propose a novel transport system architecture based on equipment level virtualization that achieves fine granular sub-port level grooming in the optical domain.

Spectrum defragmentation algorithms in elastic optical networks
Optical Switching and Networking, 2019Abstract Fragmentation in Elastic Optical Networks is an issue caused by isolated, non-aligned, and non-contiguous frequency slots that cannot be used to allocate new connection requests to the network, due to the optical layer restrictions imposed to the Routing and Spectrum Assignment (RSA) algorithms.
