Virtual Optical Network Embedding (VONE) Over Elastic Optical Networks
Journal of Lightwave Technology, 2014Based on the concept of infrastructure as a service, optical network virtualization can facilitate the sharing of physical infrastructure among different users and applications. In this paper, we design algorithms for both transparent and opaque virtual optical network embedding (VONE) over flexible-grid elastic optical 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.

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

Spectrum-sliced elastic optical networking
2013 15th International Conference on Transparent Optical Networks (ICTON), 2013Current communication environments present a wide range of traffic granularities, making it hard to use the optical spectrum efficiently under the WDM framework. In elastic networking, the WDM rigid frequency grid is replaced by a more flexible structure, in which the spectrum is organized in frequency slots, and each traffic flow is assigned to an ...

Network Fragmentation Measure in Elastic Optical Networks
2019 SBFoton International Optics and Photonics Conference (SBFoton IOPC), 2019The Elastic Optical Network (EON) with multirate transmission and supported by bandwidth-variable switching technologies has provided more efficient utilization of spectral resources, leading to improvement of the network throughput. However, EON experiences a higher degree of fragmentation than conventional fixed-grid networks because of the spectrum ...
