      Text en actes de congrés
      Accés obert
      Optimized regenerator allocation techniques select which of the already installed regenerators in a translucent network must be used in order to maximize the quality of the optical signal while minimizing the opaqueness ...
    • Regenerator allocation in WDM networks with uncertainities in the Q factor 

      Marín Tordera, Eva; Yannuzzi, Marcelo; Masip Bruin, Xavier; Serral Gracià, René; Sánchez López, Sergio (2010-06-14)
      Text en actes de congrés
      Accés obert
      The performance of the regenerator allocation algorithms in WDM networks strongly depends on the accuracy of the physical-layer information such as the Q factor. In a translucent WDM network the already installed ...
