    • Reactive and proactive routing in labelled optical burst switching networks 

      Klinkowski, Miroslaw; Careglio, Davide; Solé Pareta, Josep (2009-04)
      Article
      Accés obert
      Optical burst switching architectures without buffering capabilities are sensitive to burst congestion. The existence of a few highly congested links may seriously aggravate the network throughput. Proper network routing ...

    • Reoptimization of dynamic flexgrid optical networks after link failure repairs 

      Zotkiewicz, Mateusz; Ruiz Ramírez, Marc; Klinkowski, Miroslaw; Pioro, Michal; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2015-01-01)
      Article
      Accés obert
      In dynamic flexgrid optical networks, the usage of capacity may not be optimal due to the permanent process of setting up and tearing down connections, which, if not controlled, leads to spectrum fragmentation and, as a ...

    • RRPD strategies for a T-OBS network architecture 

      Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Solé Pareta, Josep (IEEE, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, we deal with the physical layer impairments (PLIs) in optical burst switching (OBS). In particular we present a formulation of the routing and regenerator placement and dimensioning (RRPD) problem for a ...

    • Solving large instances of the RSA problem in flexgrid elastic optical networks 

      Walkowiak, Krzysztof; Zotkiewicz, Mateusz; Klinkowski, Miroslaw; Pioro, Michal; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2016-05-01)
      Article
      Accés obert
      We present an optimization procedure that mixes advanced large-scale optimization methods and heuristics to solve large instances (with over 1.7 million integer variables) of the routing and spectrum allocation (RSA) ...

    • Spectrum allocation problem in elastic optical networks - a branch-and-price approach 

      Pioro, Michal; Klinkowski, Miroslaw; Zotkiewicz, Mateusz; Walkowiak, Krzysztof; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In the paper we present a branch and price approach to routing and spectrum allocation – a basic optimization problem in elastic optical networks. We formulate the problem as a mixed-integer program for which ...

    • Towards service orchestration between smart grids and telecom networks 

      Ricciardi, Sergio; Santos Boada, Germán; Klinkowski, Miroslaw; Careglio, Davide; Palmieri, Francesco (Springer-Verlag Berlin Heidelberg, 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In the last years, the research efforts in smart grids (SG) and telecommunication networks (TN) have been considerable but never converged to a common view and, due to the lack of strong interactions between the two worlds, ...
