Practical design of a coherent ultra-dense WDM-PON with paired DFB lasers
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Restricted access - publisher's policyA coherent WDM-PON achieving ultra-dense spectral allocation is reported. The ONU at user premises is built of coherent transceivers with two paired low-cost DFB lasers, one as local oscillator and the other as transmitter, ... -
Demonstration of monitoring and data analytics-triggered reconfiguration in partially disaggregated optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessWe demonstrate a novel agent for optical disaggregated optical networks. When the Monitoring and Data Analytics detects a degradation, it recommends the SDN controller to trigger a network reconfiguration computed by a ... -
Monitoring and data analytics-triggered reconfiguration in partially disaggregated optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessWe present ADONIS, which stands for Aggregator/Disaggregator for Optical Network equIpmentS, a novel open device agent able to construct logical network devices from (dis)aggregation of physical components in order to ... -
Optical network automation [Invited tutorial]
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference lecture
Open AccessIncreased 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 ... -
Knowledge management in optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessAutonomous network operation realized by means of control loops, where prediction from machine learning (ML) models is used as input to proactively reconfigure individual optical devices or the whole optical network, has ... -
End-to-end KPI analysis in converged fixed-mobile networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThe independent operation of mobile and fixed network segments is one of the main barriers that prevents improving network performance while reducing capital expenditures coming from overprovisioning. In particular, a ... -
Visualization tools for enhancing failure localization [Invited]
(2019)
Conference report
Open AccessThe 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
(2019)
Conference report
Open AccessDynamic 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
(2019)
Conference report
Open AccessIncreased 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
(2019)
Conference report
Open AccessSoftware 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
(2019)
Conference report
Open AccessThe 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
(2019)
Conference report
Open AccessIn 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 ...
