    • Reducing the effects of routing inaccuracy by means of prediction and an innovative link-state cost 

      Masip Bruin, Xavier; Marín Tordera, Eva; Yannuzzi, Marcelo; Serral Gracià, René; Sánchez López, Sergio (2010-05)
      Article
      Open Access
      The routing inaccuracy problem is one of the major issues impeding the evolution and deployment of Constraint- Based Routing (CBR) techniques. This paper proposes a promising CBR strategy that combines the strengths of ...
    • Performance of translucent optical networks under dynamic traffic and uncertain physical-layer information 

      Yannuzzi, Marcelo; Quagliotti, Marco; Maier, G.; Marín Tordera, Eva; Masip Bruin, Xavier; Sánchez López, Sergio; Erangoli, Walter; Tamiri, G (IEEE Computer Society Publications, 2009)
      Conference report
      Open Access
      This paper investigates the performance of translucent Optical Transport Networks (OTNs) under different traffic and knowledge conditions, varying from perfect knowledge to drifts and uncertainties in the physical-layer ...
    • Improving the Performance of Route Control Middleboxes in a Competitive Environment 

      Yannuzzi, Marcelo; Masip Bruin, Xavier; Marín Tordera, Eva; Domingo Pascual, Jordi; Fonte, Alexandre; Monteiro, Edmundo (2008-09)
      Article
      Open Access
      Multihomed subscribers are increasingly adopting intelligent route control solutions to optimize the cost and end-to-end performance of the traffic routed among the different links connecting their networks to the Internet. ...
    • Advantages of a PCE-based control plane for LISP 

      Castro Casales, Alberto; Germán Duarte, Martín; Gagliano Molla, Roque; Grampin Castro, Eduardo; Masip Bruin, Xavier; Yannuzzi, Marcelo (ACM Press. Association for Computing Machinery, 2008)
      Conference lecture
      Open Access
      The Locator/Identifier Separation Protocol (LISP) is one of the candidate solutions to address the scalability issues in inter-domain routing. The current proposals for its control plane (e.g., ALT, CONS, NERD) have various ...
    • Understanding IPv4 prefix de-aggregation: challenges for routing scalability 

      Gagliano Molla, Roque; Grampin Castro, Eduardo; Baliosian, Javier; Masip Bruin, Xavier; Yannuzzi, Marcelo (IEEE Computer Society Publications, 2009)
      Conference report
      Open Access
      The Internet has become a vast and complex infrastructure. One of the aspects of deeper concern in the community is routing scalability, which involves both the size and dynamics of the global Internet routing table. ...
    • Inter-domain Routing in Optical Networks with Wavelength Converters 

      Beshir, Anteneh; Yannuzzi, Marcelo; Kuipers, Fernando Antonio (IEEE Computer Society Publications, 2010)
      Conference report
      Open Access
      With the increasing deployment of wavelengthdivision multiplexing (WDM) optical networks, the need for advanced lightpath provisioning algorithms and protocols in a multi-domain setting is becoming evident. In order to ...
