      The online teaching support platform was changed by the Universitat Politècnica de Catalunya in 2004. Moodle, an open source software, was used in place of the prior proprietary software. The population's confinement at ...

    • The resources placement problem in a 5G hierarchical SDN control plane 

      Leyva Pupo, Irian; Cervelló Pastor, Cristina; Llorens Carrodeguas, Alejandro (Springer, 2019-01-09)
      Capítol de llibre
      Accés obert
      In this paper, we address the SDN Controllers and Virtual Network Functions (VNFs) placement problem in 5G networks. To this aim, we propose an architecture for the 5G Control Plane and a method to determine the optimal ...

    • Optimal placement of User Plane Functions in 5G networks
