Adapting the virtual network topology to near future traffic
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialThe introduction of new services requiring large and dynamic bitrate connectivity can cause changes in the direction of the traffic in metro and even core network segments along the day. This leads to large overprovisioning ... -
Big data analytics for the virtual network topology reconfiguration use case
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés restringit per política de l'editorialABNO's OAM Handler is extended with big data analytics capabilities to anticipate traffic changes in volume and direction. Predicted traffic is used to trigger virtual network topology re-optimization. When the virtual ... -
Core VNT adaptation based on the aggregated metro-flow traffic model prediction
(Optical Society of American (OSA), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialAggregation of metro-flow traffic models is proposed to obtain valid core traffic predictive models for core VNT reconfiguration when metro and core networks are independently controlled. Exhaustive simulation results ... -
Data analytics based origin-destination core traffic modelling
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialTraffic monitoring is an essential task for network operators since it allows evaluating network performance. Monitoring data from origin-destination (OD) traffic in core virtual network topologies can be collected from ... -
Designing and dimensioning networks according to traffic needs
(Universitat Politècnica de Catalunya, 2016-06-21)
Projecte Final de Màster Oficial
Accés obertNowadays network traffic is rapidly increasing, forcing operators to adapt optical networks accordingly. This poses a series of problems in order to reduce costs. In this context, this thesis presents two of these problems. ... -
