  • Optimal mapping of virtual networks with hidden hops 

    Botero Vega, Juan Felipe; Hesselbach Serra, Xavier; Fischer, Andreas; de Meer, Hermann (2012-12-01)
    Article
    Open Access
    Network virtualization has emerged as a solution for the Internet inability to address the required challenges caused by the lack of coordination among Internet service providers for the deployment of new services. The ...
  • Optimization model for bandwidth allocation in a network virtualization environment 

    Botero Vega, Juan Felipe; Hesselbach Serra, Xavier (2009)
    Conference report
    Open Access
    Bandwidth allocation is one of the main problems in network virtualization. Mechanisms to allocate bandwidth may avoid bottlenecked virtual links. This paper proposes a model based on optimization theory, to distribute the ...
