    • An architecture to support autonomic slice networking 

      Velasco Esteban, Luis Domingo; Gifre Renom, Lluís; Izquierdo Zaragoza, José Luis; Paolucci, Francesco; Vela, Alba P.; Sgambelluri, Andrea; Ruiz Ramírez, Marc; Cugini, Filippo (2017-09-01)
      Article
      Open Access
      IEEE Network slices combine resource virtualization with the isolation level required by future 5G applications. In addition, the use of monitoring and data analytics help to maintain the required network performance, while ...
    • Applying data visualization for failure localization 

      Vela, Alba P.; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2018)

      Data visualization is applied to BER measures in a bigdata repository. Bubble charts are produced to identify lightpaths with increasing BER and spectrum color maps are then used to identify the most likely degraded link
    • BER degradation detection and failure identification in elastic optical networks 

      Vela, Alba P.; Ruiz Ramírez, Marc; Fresi, Francesco; Sambo, Nicola; Cugini, Filippo; Meloni, Gianluca; Poti, Luca; Velasco Esteban, Luis Domingo; Castoldi, Piero (2017-08-30)
      Article
      Open Access
      IEEE Optical connections support virtual links in MPLS-over-optical multilayer networks and therefore, errors in the optical layer impact on the quality of the services deployed on such networks. Monitoring the performance ...
    • Learning from the optical spectrum: soft-failure identification and localization 

      Velasco Esteban, Luis Domingo; Shariati, Mohammad Behnam; Vela, Alba P.; Comellas Colomé, Jaume; Ruiz Calvo, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Restricted access - publisher's policy
      The availability of coarse-resolution cost-effective Optical Spectrum Analyzers (OSA) allows its widespread deployment in operators' networks. In this paper, several machine learning approaches for failure identification ...
    • Monitoring and data analytics: Analyzing the optical spectrum for soft-failure detection and identification 

      Shariati, Mohammad Behnam; Vela, Alba P.; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference lecture
