    • Automated end to end Carrier Ethernet provisioning over a disaggregated WDM metro network with a hierarchical SDN control and monitoring platform 

      Morro, Roberto; Lucrezia, Francesco; Gomes, P.; Casellas Regi, Ramón; Giorgetti, Alessio; Velasco Esteban, Luis Domingo; Riccardi, Emilio; Chiadò Piat, Anna; Percelsi, Alessandro; Pedro, João; Gifre Renom, Lluís; Sgambelluri, Andrea; Risso, Fulvio; Marchetto, Guido (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Open Access
      This demo shows how a hierarchical control plane of ONOS SDN controllers orchestrates the dynamic provisioning of end-to-end Carrier Ethernet circuits on a composite network, programming the whole data path from the CPE ...
    • 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 (2021-09)
      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 ...
    • Dynamic and efficient point-to-point and point-to-multipoint communications by slicing the optical constellation 

      Iqbal, Masab; Ruiz Ramírez, Marc; Costa, Nelson; Napoli, Antonio; Pedro, João; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference lecture
      Open Access
      Optical Constellation Slicing is proposed to convey heterogenous traffic from a source to multiple destinations, while supporting dynamic capacity allocation. Illustrative numerical results reveal the potential of the ...
    • Lightweight optical constellation modeling by concatenating artificial neural networks 

      Sequeira, Diogo Gonçalo; Ruiz Ramírez, Marc; Costa, Nelson; Napoli, Antonio; Pedro, João; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      A lightweight optical constellations modeling method based on concatenating ANNs is proposed. Statistical validation of the reproduced constellations is shown. The method accelerates data generation and facilitates detecting ...
    • LPsec: a fast and secure cryptographic system for optical connections 

      Iqbal, Masab; Velasco Esteban, Luis Domingo; Costa, Nelson; Napoli, Antonio; Pedro, João; Ruiz Ramírez, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2022-04)
      Article
      Open Access
      High capacity and low latency of optical connections are ideal for supporting current and future communication services, including 5G and beyond. Although some of those services are already secured at the packet layer using ...
