After failure repair optimization in dynamic flexgrid optical networks
(The Optical Society (OSA), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialWe introduce the problem of reoptimizing the network after a link failure has been repaired as an effective way for reducing capacity usage and improving network performance. Numerical results show gains higher than 42%. -
How national IP/MPLS networks can benefit from flexgrid optical technology?
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Text en actes de congrés
Accés obertWe design a 1113-node network and show that the optimum is a large Flexgrid core serving small metro areas. Cost savings of about 31% in the core and 23% in the metro are shown. -
Impact of multi-wavelength sliceable transponders in elastic optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés obertThe utilization of sliceable bandwidth variable transponders based on multi-wavelength technology is evaluated in EONs. A routing and spectrum assignment scheme is proposed specifically designed to consider the constraints ... -
Inter-core crosstalk impact on migration planning from elastic optical networks to spectrally-spatially flexible optical networks
(Optical Society of American (OSA), 2019)
Text en actes de congrés
Accés obertWe study inter-core crosstalk (ICXT) impact on migration planning toward spectrally-spatially flexible optical networks considering 22-core multi-core fiber. Results reveal that 55-70% of links need to be upgraded when ...
