      Serral Gracià, René; Marín Tordera, Eva; Yannuzzi, Marcelo; Masip Bruin, Xavier; Sánchez López, Sergio (2010)
      Conference report
      Open Access
      This paper presents a Cross-layer Network Management System (NMS) that allows Service Providers (SPs) to perform cost-effective network resource reservations with their Network Operators (NOs). The novelty of our NMS is ...
    • Towards an efficient Service Level Agreement assessment 

      Serral Gracià, René; Labit, Yann; Domingo Pascual, Jordi; Owezarski, Philippe (IEEE Computer Society Publications, 2009)
      Conference report
      Open Access
      On-line end-to-end Service Level Agreement (SLA) monitoring is of key importance nowadays. For this purpose, past recent researches focused on measuring (when possible) or estimating (most of the times) network QoS or ...
    • An Approach to a Fault Tolerance LISP Architecture 

      Martínez Manzanilla, Anny Gabriela; Ramírez, Wilson; Germán Duarte, Martín; Serral Gracià, René; Marín Tordera, Eva; Yannuzzi, Marcelo; Masip Bruin, Xavier (Springer Verlag, 2011)
      Conference report
      Open Access
      Next Generation Internet points out the challenge of addressing "things" on both a network with (wired) and without (wireless) infrastructure. In this scenario, new efficient and scalable addressing and routing schemes ...
    • Bridging the Interoperability Gap Between the Internet and Optical Network Management Systems 

      Yannuzzi, Marcelo; Masip Bruin, Xavier; González de Dios, Óscar; García Argos, Carlos; Maciejewski, Maciej; Altmann, Jorn (IEEE Computer Society Publications, 2011)
      Conference report
      Restricted access - publisher's policy
      Despite the efforts made towards the convergence of packet and circuit switched technologies, the isolation between the Internet and the optical Network Management Systems (NMSs) remains unsolved. Today, carriers have ...
    • Quality of experience based provisioning for service providers 

      Serral Gracià, René; Marín Tordera, Eva; Yannuzzi, Marcelo; Masip Bruin, Xavier; Sánchez López, Sergio (2009-12-14)
      Conference report
      Open Access
      Nowadays Network Operators (NOs) are providing service guaranties to customers by largely overprovisioning their networks, but as the Internet keeps growing, this approach is unveiling important issues in terms of cost and ...
    • Modeling physical-layer impairments in multi-domain optical networks 

      Yannuzzi, Marcelo; Marín Tordera, Eva; Serral Gracià, René; Masip Bruin, Xavier; González de Dios, Óscar; Jimenez Chico, Javier; Verchere, Dominique (IEEE Computer Society Publications, 2011)
      Conference report
      Restricted access - publisher's policy
      The advantages of optical transparency are still confined to the boundaries of a domain, since the optical signals are subject to O/E/O conversions at the border nodes that separate two optical domains. The extension ...
    • Cross-talk effects on the Regenerator Allocation optimization 

      Marín Tordera, Eva; Masip Bruin, Xavier; Yannuzzi, Marcelo; Serral Gracià, René; Sánchez López, Sergio (2011)
      Conference report
      Open Access
      This paper studies the impact of considering crosstalk effects in the IA-RWA process and in the regenerator allocation algorithms. First of all, we evaluate if the regenerator allocation optimization is still useful when ...
    • Cross-layer multimedia quality enforcement through user aware information in wireless networks
