GNPy: an open source application for physical layer aware open optical networks
Alessio Ferrari,Mark Filer,Karthikeyan Balasubramanian,Yawei Yin,Esther Le Rouzic,Jan Kundrat,Gert Grammel,Gabriele Galimberti,Vittorio Curri +8 more
TL;DR: GNPy is validated by feeding it with data from the network controller and comparing the results to experimental measurements on mixed-fiber, Raman-amplified, multivendor scenarios over the full C-band, showing excellent accuracy in predicting both the optical signal-to-noise ratio and the generalized signal- to-no noise ratio (GSNR).
Journal ArticleDOI
Spectrum fragmentation issue in flexible optical networks: analysis and good practices
TL;DR: This work presents an exhaustive analysis and an accurate evaluation for spectrum fragmentation issue in flexible optical networks and proposes new metric for fragmentation measurements and some approaches to address such a problem.
Proceedings ArticleDOI
Evaluation of power rating of core network equipment in practical deployments
Ward Van Heddeghem,Filip Idzikowski,Esther Le Rouzic,Jean Yves Mazeas,Hubert Poignant,Suzanne Salaun,Bart Lannoo,Didier Colle +7 more
TL;DR: It is shown that, over the equipment's lifetime, for IP/MPLS routers it is reasonable to almost double the optimal power rating value under real-life equipment filling conditions, and power measurements on IP routers and Optical Line Amplifiers show that their power consumption marginally depends on traffic load.
Journal ArticleDOI
Sleep modes effectiveness in backbone networks with limited configurations
TL;DR: A practical implementation of sleep mode strategies for network operators is to define, on the basis of typical traffic trend, few configurations to be activated in specific time instants.
Journal ArticleDOI
TREND in energy-aware adaptive routing solutions
Filip Idzikowski,Edoardo Bonetto,Luca Chiaraviglio,Antonio Cianfrani,Angelo Coiro,Raul Duque,Felipe Jimenez,Esther Le Rouzic,Francesco Musumeci,Ward Van Heddeghem,Jorge Lopez Vizcaino,Yabin Ye +11 more
TL;DR: This work looks at the electrical and optical layers of IP-over-WDM networks, and presents a list of evaluation criteria for energy- aware adaptive routing solutions (EA-ARSs) from the perspective of a network operator.
