Protection in elastic optical networks
IEEE Network, 2015In this article, we analyze gains resulting from the use of EON architectures with special focus on transportation of cloud-ready and content-oriented traffic in the context of network resilience. EONs are a promising approach for future optical transport networks and, apart from improving the network spectral efficiency, bring such new capabilities as

Elastic Optical Networks: Introduction
Journal of Optical Communications and Networking, 2016This short introductory paper sets the scene for this special edition of the Journal of Optical Communications and Networking, which is focused on elastic optical networks (EONs). A brief overview of the field is given, followed by a summary of the five invited papers. This special edition is designed to provide a review of current EON technology.

Optimal Provisioning of Elastic Optical Networks
2020 22nd International Conference on Transparent Optical Networks (ICTON), 2020The explosive growth of emerging applications and networking paradigms (e.g., Internet of Things (Iot), Software Defined Network (SDN), 5G slicing) leads to the rapid development of elastic optical networks (EON) for the next generation backbone networks.

Abstract In WDM networks using a fixed frequency grid, transmission rates can vary for different connections, leading to inefficient bandwidth utilization in optical fibers with lower-rate connections using wide frequency slots. In elastic optical networks (EONs), the frequency grid is made flexible, thereby improving the effective ...

Optical datacenter networks with elastic optical switches
2017 IEEE International Conference on Communications (ICC), 2017Four variants of the optical data center network architecture (DCN1 — DCN4) based on optical circuit switching and elastic optical switching elements are proposed. For each variant theoretical limits for non-blocking operation have been derived and proved.

Elastic optical networking: An operators perspective
2014 The European Conference on Optical Communication (ECOC), 2014Although there is perhaps an acceptance that EON has benefits, there is a debate about whether a full flexgrid implementation is required to achieve those benefits. Current industry debate addressed in this paper relates to when is the most appropriate time for carriers to: (a) install flexgrid ready components, and (b) enable them and start using the ...

Multilayer restoration in elastic optical networks
2015 International Conference on Optical Network Design and Modeling (ONDM), 2015Optical restoration is known to be an effective way to save on network overall cost, using the same available equipment previously used before the failure occurs. However, when backup paths are too long, some regenerators can be required bringing into question the expected gain. In this work, we show that transponder datarate elasticity is a successful

On the Load Normalization in Elastic Optical Networks
2019 21st International Conference on Transparent Optical Networks (ICTON), 2019In recent years, the elastic optical networks (EONs) emerged as a potential technology to support a great variety of bandwidth-consuming applications in core and metropolitan area networks. Within EONs framework, it is possible to choose the modulation formats and/or bandwidth requirements depending on the network available resources and on the ...
