    The ever increasing IP traffic volume has finally brought to light the high inefficiency of current wavelength-routed rigid-grid networks in matching the client layer requirements. Such an issue results in the deployment ...
  • On the physical impairments constraint in OBS networks 

    Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Solé Pareta, Josep (2010)
    Conference report
    Open Access
    The introduction of sub-wavelength switching is one of the main objectives of the future transparent optical mesh networks. One strong candidate is Optical Burst Switching (OBS) which improves the resource utilisation by ...
  • RRPD strategies for a T-OBS network architecture 

    Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Solé Pareta, Josep (IEEE, 2011)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • Survivable IP/MPLS-Over-WSON multilayer network optimization 

    Ruiz Ramírez, Marc; Pedrola Escribà, Òscar; Velasco Esteban, Luis Domingo; Careglio, Davide; Fernández Palacios, Juan Pedro; Junyent Giralt, Gabriel (Optical Society of America, 2011-08-01)
    Article
    Open Access
    Network operators are facing the problem of dimensioning their networks for the expected huge IP traffic volumes while keeping constant or even reducing the connectivity prices. Therefore, new architectural solutions able ...
