  • Visualization tools for enhancing failure localization [Invited] 

    Pérez Vela, Alba; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (2019)
    Conference report
    Open Access
    The use of data visualization techniques is explored to guide human operators in failure localization tasks. In this paper, we consider the case where a subset of lightpaths’ experience gradual BER degradation. We aim at ...
  • Smart filterless optical networks based on optical spectrum analysis 

    Ruiz Ramírez, Marc; Sgambelluri, Andrea; Cugini, Filippo; Velasco Esteban, Luis Domingo (2019)
    Conference report
    Open Access
    Dynamic network operations can produce power fluctuations of the established connections in filterless optical networks. In addition, the gridless nature of filterless networks make that some ...
  • Monitoring and data analytics for optical networking 

    Velasco Esteban, Luis Domingo; Ruiz Ramírez, Marc (2019)
    Conference report
    Open Access
    Increased levels of automation will be necessary in view of more stringent performance requirements that next generation optical transport networks need to support in a near term, not only for high capacity, but, even more ...
  • Interfaces for monitoring and data analytics systems 

    Gifré Renom, Lluís; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (2019)
    Conference report
    Open Access
    Software defined networks (SDN) represents one of the most relevant innovations in recent years for the telecom industry. Major operators are planning to progressively migrate their transport networks, including ...
  • Generation and analysis of service-based traffic flows 

    Bernal Escribano, Álvaro; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (2019)
    Conference report
    Open Access
    The rapid availability of new services makes that network operators cannot exhaustively test their impact on the network or anticipate any capacity exhaustion. This situation will be worse with the imminent introduction ...
  • Distributed and centralized options for self-learning 

    Tabatabaeimehr, Fatemehsadat; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (2019)
    Conference report
    Open Access
    In general, the availability of enough real data from real fog computing scenarios to produce accurate Machine Learning (ML) models is rarely ensured since new equipment, techniques, etc., are continuously ...
  • Autonomous operations in optical networks 

    Pérez Vela, Alba; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (2019)
    Conference report
    Open Access
    Machine Learning (ML) has already proven its benefits for network operation, being a sub-domain of artificial intelligence, it is highly suitable for complex system representation. In this paper, ...
  • Autonomic content delivery network service 

    Velasco Esteban, Luis Domingo; Gifré Renom, Lluís; Ruiz Ramírez, Marc (2019)
    Conference report
    Open Access
    We focus on a use case where a virtualized Content Delivery Network (CDN) service autonomously adapts to the load by requesting the instantiation of new VMs in selected leaf cache nodes, as well as by ...
  • An iris based lungs pre-diagnostic system 

    Hussain, Tassadaq; Haider, Amna; Muhammad, Abdul Malik; Agha, Areeb; Khan, Bilal; Rashid, Fawad; Raza, Muhammad Saad; Din, Moainud; Khan, Mehran; Ullah, Sami; Ahmed, Abdelmalik Taleb; Ayguadé Parra, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    Human lungs are essential respiratory organs. Different Obstructive Lung Diseases (OLD) such as bronchitis, asthma, lungs cancer etc. affects the respiration. Diagnosing OLD in the initial stage is better than diagnosing ...
  • Soft-failure localization and time-dependent degradation detection for network diagnosis 

    Barzegar, Sima; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (2020)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • Collective self-learning by exchanging ML models 

    Ruiz Ramírez, Marc; Boitier, Fabien; Layec, Patricia; Velasco Esteban, Luis Domingo (The Institution of Engineering and Technology (IET), 2019)
    Conference report
    Open Access
    Collective self-learning based on Machine Learning (ML) model sharing and combination is proposed to accelerate ML-based algorithm deployment. The considered architecture is presented, together with different alternatives ...
  • Distributed access control with blockchain
