Optical datacenter networks with elastic optical switches

2017 IEEE International Conference on Communications (ICC), 2017
Four 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), 2014
Although 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), 2015
Optical 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

Partial defragmentation in elastic optical networks

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014
In elastic optical networks, the lightpaths setup and tear down processes may cause the so-called spectrum fragmentation issue, degrading spectrum utilization, increasing lightpath rejection ratio, and this is especially critical under dynamic traffic scenarios.

On the Load Normalization in Elastic Optical Networks

2019 21st International Conference on Transparent Optical Networks (ICTON), 2019
In 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 ...
