  • A distributed, parallel, and generic virtual network embedding framework 

    Beck, Michael Till; Fischer, Andreas; de Meer, Hermann; Botero Vega, Juan Felipe; Hesselbach Serra, Xavier (2013)
    Conference report
    Restricted access - publisher's policy
    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

    Network virtualization is recognized as an enabling technology for the Future Internet. Applying virtualization of network resources leads to the problem of mapping virtual resources to physical resources, known as “Virtual ...
  • Energy efficient virtual network embedding 

    Botero Vega, Juan Felipe; Hesselbach Serra, Xavier; Duelli, Michael; Schlosser, Daniel; Fischer, A.; de Meer, Hermann (2012-05)
    Article
    Restricted access - publisher's policy
    Waste of energy due to over-provisioning and overdimensioning of network infrastructures has recently stimulated the interest on energy consumption reduction by Internet Service Providers (ISPs). By means of resource ...
  • Energy-efficient wireless mesh infrastructures 

    Al-Hazmi, Y.; de Meer, Hermann; Hummel, Karin Anna; Meyer, Harald; Meo, Michela; Remondo Bueno, David (2011-03)
    Article
    Restricted access - publisher's policy
    The Internet comprises access segments with wired and wireless technologies. In the future, we can expect wireless mesh infrastructures (WMIs) to proliferate in this context. Due to the relatively low energy efficiency ...
