  • An architecture to support autonomic slice networking 

    Velasco Esteban, Luis Domingo; Gifre Renom, Lluís; Izquierdo Zaragoza, José Luis; Paolucci, Francesco; Vela, Alba P.; Sgambelluri, Andrea; Ruiz Ramírez, Marc; Cugini, Filippo (2017-09-01)
    Article
    Open Access
    IEEE Network slices combine resource virtualization with the isolation level required by future 5G applications. In addition, the use of monitoring and data analytics help to maintain the required network performance, while ...
  • Autonomic disaggregated multilayer networking 

    Gifre Renom, Lluís; Izquierdo Zaragoza, José Luis; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2018-05-01)
    Article
    Open Access
    Focused on reducing capital expenditures by opening the data plane to multiple vendors without impacting performance, node disaggregation is attracting the interest of network operators. Although the software-defined ...
