Split spectrum-enabled route and spectrum assignment in elastic optical networks
Optical Switching and Networking, 2014 The Split Spectrum Approach (SSA) in elastic optical networks is based on splitting a demand into smaller sub-signals when a blocking situation arises, either due to the lack of spectral resources or transmission reach reasons. In this paper, we propose a mechanism based on a Mixed Integer Linear Programming (MILP) formulation for efficiently serving ...

Routing and Spectrum Assignment for Dual Failure Path Protected Elastic Optical Networks
IEEE Access, 2016 We present the design of a dual failure protected elastic optical network (EON) for different sharing capabilities of protection lightpaths. Routing and spectrum assignment (RSA) is considered for such a network so as to minimize the maximum number of ...

Dynamic Routing and Spectrum Assignment with Non-Disruptive Defragmentation [PDF]
, 2014 L'augmentation du trafic Internet motive une évolution des réseaux WDM traditionnels vers les réseaux optiques élastiques (Elastic Optical Networks, EON). Les EONs sont conçus pour optimiser l'utilisation des ressources optiques; ils permettent l'attribution de bandes de largeurs quelconques et offrent ainsi plus de souplesse que les réseaux WDM avec ...

Spectrum Aware Virtual Coordinates Assignment and Routing in Multihop Cognitive Networks
2015 IFIP Networking Conference (IFIP Networking), 2015 We propose Spectrum Aware Virtual Coordinate (SAViC) for multi hop cognitive radio network (CRN) to facilitate geographic routing. The proposed virtual coordinates (VC) of any two secondary users reflect both geographic distance and opportunistic spectrum availability between them.
