Spectral Reallocation In Lightpaths Encompassing The Most Fragmented Link Of Elastic Optical Networks

, 2017
Dynamic allocation and release of lightpaths cause spectral fragmentation and degrade the bandwidth occupation in elastic optical networks (EON). Spectral reallocation and defragmentation strategies are key issues to minimize this problem and should be ...

Analytical Model of a Single Link of Elastic Optical Networks

IEEE Access, 2022
This article discusses and evaluates a model of resources to which multiservice traffic is offered. The initial assumption for the model is that calls of particular traffic classes are always serviced in neighboring allocation units of the resources ...

Virtual network embedding and reconfiguration in elastic optical networks [PDF]

2014 IEEE Global Communications Conference, 2014
Recent innovations in Network Virtualization and Elastic Optical Networks (EONs) enable flexible deployment of optical networks as a service. However, one open challenge is how to embed Virtual Optical Network (VON) requests onto the physical substrate network to maximize the sharing of physical resources, which is the so called Virtual Network ...

Efficient multicasting technique for elastic optical network [PDF]

IET Networks, 2020
Abstract The elastic optical network (EON) is the latest solution to increase the capacity of optical networks, as a response to the ever‐increasing demand for traffic. To meet the EON mission, new algorithms and frameworks need to be designed. In this paper, a new algorithm based on EON is proposed that employs a subtree‐based scheme

Subband switching on optical supperchannel for elastic optical networks

, 2013
We propose subband-based optical networking on optical OFDM/SCFDM superchannel in elastic optical networks. Feasibilities of add-drop, switching, conversion and multicasting functionalities on optical superchannel are experimentally demonstrated.
