    • Adaptation of the residual signal for filter failure detection in scenarios with multiple filter types 

      Barzegar, Sima; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (2019)
      Conference report
      Open Access
      To monitor the optical spectra of outgoing links, Optical Spectrum Analyzers (OSA) can deployed in the optical nodes acquiring the optical spectra of outgoing links and analyzing optical signals to detect ...
    • Autonomous and energy efficient lightpath operation based on digital subcarrier multiplexing 

      Velasco Esteban, Luis Domingo; Barzegar, Sima; Sequeira, Diogo Gonçalo; Ferrari, Alessio; Costa, Nelson; Curri, Vittorio; Pedro, João; Napoli, Antonio; Ruiz Ramírez, Marc (2021-03-09)
      Article
      Open Access
      The massive deployment of 5G and beyond will require high capacity and low latency connectivity services, so network operators will have either to overprovision capacity in their transport networks or to upgrade the optical ...
    • Reinforcement learning-based autonomous multilayer network operation 

      Barzegar, Sima; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Open Access
      We propose an Intent-Based Networking solution based on Reinforcement Learning (RL). RL-based intents with specific operational objectives and coordinated operation between network layers are developed. Results show service ...
    • Soft-failure localization and device working parameters estimation in disaggregated scenarios 

      Barzegar, Sima; Virgillito, E.; Ruiz Ramírez, Marc; Ferrari, A.; Napoli, Antonio; Curri, Vittorio; Velasco Esteban, Luis Domingo (2020)
      Conference report
      Restricted access - publisher's policy
      A soft-failure localization and key working parameters estimation system is proposed for network diagnosis and maintenance. We show that a double analysis of monitoring data and estimated working parameters ...
    • Soft-failure localization and time-dependent degradation detection for network diagnosis 

      Barzegar, Sima; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (2020)
      Conference report
      Open Access
      In optical networks, degradation of the Quality of Transmission (QoT) can be the outcome of soft-failures in optical devices, like Optical Transponders, Wavelength Selective Switches (WSS) and Optical ...
