    In this paper we deal with the survivable internet protocol (IP)/multi-protocol label switching (MPLS)-over-wavelength switched optical network (WSON) multi-layer network optimization problem (SIMNO). This problem entails ...
  • 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

    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 ...
  • Coordinated Computation of Multi-layer Paths via Inter-layer PCE Communication: Standards, Interoperability and Deployment 

    Chamania, Mohit; González de Dios, Óscar; López, Víctor; Cuaresma, Marta; Drogon, Marek; Jukan, Admela; Masip Bruin, Xavier; Yannuzzi, Marcelo (2012)
    Conference report
    Open Access
    The Path Computation Element (PCE) is positioned nowadays as one of the solutions that almost every carrier will eventually deploy. The PCE architecture as well as a number of components, including the PCE Communication ...
  • Finding an objective cost for sliceable flexgrid transponders 

    Velasco Esteban, Luis Domingo; González de Dios, Óscar; López, Víctor; Fernández Palacios, Juan Pedro; Junyent Giralt, Gabriel (The Optical Society (OSA), 2014)
    Conference report
    Open Access
    We analyze the objective cost of SBVTs as a function of the traffic conveyed by IP/MPLS-over-flexgrid networks. Optimal results show that cost increment with respect to BVTs is related to the aggregation level.
  • 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

    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 ...
