Quantifying dynamic traffic in Elastic Optical networks

2017 19th International Conference on Transparent Optical Networks (ICTON), 2017
This work is focused on the characterization of the traffic allocated in Elastic Optical backbone networks when different dynamic traffic profiles are generated. Extensive simulations are done to statistically model the real-time traffic carried by this kind of networks.

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.

Code rate optimization in elastic optical networks [PDF]

2015 European Conference on Optical Communication (ECOC), 2015
We combine adaptive coding with nonlinear impairment-aware routing and spectrum allocation problem in elastic optical networks. An integer linear program formulation and low-complexity heuristics are proposed. Results indicate that over 50% bandwidth reduction can be obtained due to code-rate optimization.

Soft Failure Localization in Elastic Optical Networks

2018 20th International Conference on Transparent Optical Networks (ICTON), 2018
Soft failure localization to early detect service level agreement violations is of paramount importance in elastic optical networks (EONs), while it allows anticipating possible hard failure events. Nowadays, effective and automated solutions for soft failure localization during lightpaths' commissioning testing and operation are still missing. In this

IDEALIST data plane solutions for elastic optical networks

, 2022
S.355-359The elastic optical networks paradigm offers a competitive solution in terms of resource utilization to cope with the ever-increasing traffic demand. Specifically, the ability to make a number of previously fixed transmission parameters tunable,

Rearrangeable and Repackable S-W-S Elastic Optical Networks for Connections with Limited Bandwidths

Applied Sciences, 2020
Elastic optical networks flexibly allocate bandwidth to a connection for improving utilization efficiency. The paper considers an optical node architecture that is similar to a three-stage Clos network for elastic optical networks.

Rearrangeability of 2×2 W-S-W Elastic Switching Fabrics with Two Connection Rates

Journal of Telecommunications and Information Technology, 2018
The rearreangeable conditions for the 2×2 threestage switching fabric of a W-S-W architecture for elastic optical switches are considered in this paper. Analogies between the switching fabric considered and the three-stage Clos network are shown. On the
