    • A modular simulation tool of an orchestrator for allocating virtual resources in SDN 

      García García, Aurelio Javier; Cervelló Pastor, Cristina; Jiménez Agudelo, Yury Andrea (2014-04)
      Article
      Open Access
      Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) are technologies for enabling innovative network architectures. Nevertheless, a fundamental problem in instantiation of Virtual Networks (VNs), ...

    • Defining a network management architecture 

      Jiménez Agudelo, Yury Andrea; Cervelló Pastor, Cristina; García García, Aurelio Javier (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report

      This work proposes an algorithm called k-Critical Node to solve the controller placement problem in Software Defined Networks. K-Critical finds the minimum number of controllers to satisfy a target communication delay ...

    • Diseño SDN/NFV con retardo balanceado entre orquestador, controladores y elementos de red 

      García García, Aurelio; Cervelló Pastor, Cristina; Jiménez Agudelo, Yury Andrea (2015)
      Conference lecture
      Restricted access - publisher's policy
      El eje central de esta investigación se concreta en el desarrollo de una metodología específica que consigue seleccionar la ubicación óptima de los nodos de control en las redes SDN y NFV. El objetivo es solventar las ...

    • Dynamic resource discovery protocol for software defined networks 

      Jiménez Agudelo, Yury Andrea; Cervelló Pastor, Cristina; García García, Aurelio Javier (2015-05-01)
      Article
      Open Access
      In Software Defined Networking (SDN), the network management is logically centralized but physically distributed among the controllers to improve the scalability compared with a completely centralized model. As an alternative ...

    • 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 ...

    • Scalability and robustness in software-defined networking (SDN) 

      Jiménez Agudelo, Yury Andrea (Universitat Politècnica de Catalunya, 2016-07-06)
      Doctoral thesis
      Open Access
      The simplicity of Internet design has led to enormous growth and innovation. In recent decades several network technologies, services and applications have appeared, which demand specific network requirements for their ...
