  • 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 ...
  • Experimental demonstration of an active stateful PCE performing elastic operations and hitless defragmentation 

    Castro Casales, Alberto; Paolucci, Francesco; Fresi, Francesco; Imran, Muhammad; Bhowmik, Bishanka; Berrettini, Gianluca; Meloni, Gianluca; Giorgetti, Alessio; Cugini, Filippo; Velasco Esteban, Luis Domingo; Poti, Luca; Castoldi, Piero (2013)

    An experimental demonstration of active stateful PCE for flexgrid networks is presented. The PCE enables elastic operations on established connections and, when required, performs hitless defragmentation of spectrum ...
  • Experimental demonstration of multi-vendor and multi-domain elastic optical network with data and control interoperability over a pan-european test-bed 

    González de Dios, Oscar; Casellas Regi, Ramón; Paolucci, Francesco; Napoli, Antonio; Gifre Renom, Lluís; Dupas, Arnaud; Hugues Salas, Emilio; Morro, Roberto; Belotti, Sergio; Meloni, Gianluca; Rahman, Talha; López Álvarez, Victor; Martínez Rivera, Ricardo Victor; Fresi, Francesco; Bohn, Marc; Yan, Shuangyi; Velasco Esteban, Luis Domingo; Layec, Patricia; Fernández Palacios, Juan Pedro (2016-04-01)
    Article
    Open Access
    The operation of multidomain and multivendor EONs can be achieved by interoperable sliceable bandwidth variable transponders (S-BVTs), a GMPLS/BGP-LS-based control plane, and a planning tool. The control plane is extended ...
  • Superfilter technique in SDN-controlled elastic optical networks 

    Paolucci, Francesco; Cugini, Filippo; Fresi, Francesco; Meloni, Gianluca; Giorgetti, Alessio; Sambo, Nicola; Poti, Luca; Castro Casales, Alberto; Velasco Esteban, Luis Domingo; Castoldi, Piero (Institute of Electrical and Electronics Engineers (IEEE), 2015-02-01)
