    In this article we focus on lightpath adaptation under time-varying traffic in a dynamic elastic optical network (EON) implementing flexgrid optical technology. In the considered scenario, a number of IP/MPLS metro area ...
  • Metaheuristic hybridizations for the regenerator placement and dimensioning problem in sub-wavelength switching optical networks 

    Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Velasco Esteban, Luis Domingo; Bergman, K.; Solé Pareta, Josep (Elsevier, 2013-02-01)

    Physical layer impairments severely limit the reach and capacity of optical systems, thereby hampering the deployment of transparent optical networks (i.e., no electrical signal regenerators are required). Besides, the ...
  • Optimization models for flexgrid elastic optical networks 

    Zotkiewicz, Mateusz; Pioro, Michal; Ruiz Ramírez, Marc; Klinkowski, Miroslaw; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report

    In the paper we present integer programming (IP) optimization models for flexgrid elastic optical networks (EON). We consider several different basic assumptions regarding flexibility of EON that lead to a variety of IP ...
  • 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)
    Conference report

    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, ...
  • Valid inequalities for the routing and spectrum allocation problem in elastic optical networks 

    Klinkowski, Miroslaw; Pioro, Michal; Zotkiewicz, Mateusz; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    We deal with a natural integer-linear programming formulation of the routing and spectrum allocation (RSA) problem in elastic optical networks. We focus on strengthening the formulation with valid inequalities (cuts). For ...
