    Software-Defined Networking and Network Functions Virtualisation has brought a revolution within the telecom market landscape. Initial proof-of-concept prototypes for NFV-enabled solutions are being developed at the same ...
  • On the controller placement for designing a distributed SDN control layer 

    Jiménez Agudelo, Yury Andrea; Cervelló Pastor, Cristina; García García, Aurelio Javier (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference lecture
    Open Access
    The software-defined network (SDN) advocates a centralized network control, where a controller manages a network from a global view of the network. Large SDN networks may consist of multiple controllers or controller domains ...

    One of the main challenges of network virtualization is the mapping of virtual network demands to physical network resources, commonly known as the virtual network embedding (VNE) problem. This paper introduces DPVNE, a ...
  • A generic architecture for Demand Response: the All4Green approach 

    Basmadjian, Robert; Lovasz, Gergö; Beck, Michael Till; de Meer, Hermann; Hesselbach Serra, Xavier; Botero Vega, Juan Felipe; Klingert, Sonja; Pérez Ortega, María; López, Juan Carlos; Stam, Andries; van Krevelen, Rick; di Girolamo, marco (Institute of Electrical and Electronics Engineers (IEEE), 2013)
