  • Experimental demonstration of multi-vendor and multi-domain elastic optical network with data and control interoperability over a pan-european test-bed 

    González de Dios, Oscar; Casellas Regi, Ramón; Paolucci, Francesco; Napoli, Antonio; Gifre Renom, Lluís; Dupas, Arnaud; Hugues Salas, Emilio; Morro, Roberto; Belotti, Sergio; Meloni, Gianluca; Rahman, Talha; López Álvarez, Victor; Martínez Rivera, Ricardo Victor; Fresi, Francesco; Bohn, Marc; Yan, Shuangyi; Velasco Esteban, Luis Domingo; Layec, Patricia; Fernández Palacios, Juan Pedro (2016-04-01)
    Article
    Open Access
    The operation of multidomain and multivendor EONs can be achieved by interoperable sliceable bandwidth variable transponders (S-BVTs), a GMPLS/BGP-LS-based control plane, and a planning tool. The control plane is extended ...
  • Signal to noise ratio in nonlinear optical amplification process 

    Soneira Ferrando, M. José; Ruiz Moreno, Sergio (1990-01)
    Article
    Open Access
    In this communication, one looks at the influence of the saturation process over the statistical fluctuations (signal to noise ratio) of the optical power at the output of a travelling wave semiconductor optical amplifier ...
  • Optimum carrier to signal power ratio for remote heterodyne DD-OFDM in PONs 

    Cano Valadéz, Iván Nicolás; Santos Blanco, M. Concepción; Prat Gomà, Josep Joan (2013-07)
    Article
    Restricted access - publisher's policy
    The carrier to signal power ratio (CSPR) in a directdetection optical orthogonal frequency division multiplexing (OFDM) system based on remote heterodyne scheme is optimized in a passive optical network (PON) downlink. ...
  • Restoration in optical cloud networks with relocation and services differentiation 

    Natalino da Silva, Carlos; Wosinska, Lena; Spadaro, Salvatore; Costa, J. C. W. A.; Frances, Carlos; Monti, Paolo (Institute of Electrical and Electronics Engineers (IEEE), 2016-02-01)
    Article
    Open Access
    Optical cloud networks allow for the integrated management of both optical and IT resources. In this paradigm, cloud services can be provisioned in an anycast fashion; i.e., only the source node asking for a service is ...
  • LIGHTNESS: a function-virtualizable software defined data center network with all-optical circuit/packet switching 

    Saridis, G. M.; Peng, S.; Yan, Yan; Aguado, A.; Guo, B.; Arslan, M.; Jackson, C.; Miao, W.; Calabretta, N.; Agraz Bujan, Fernando; Spadaro, Salvatore; Bernini, G.; Ciulli, N.; Zervas, G.; Nejabati, R.; Simeonidou, D. (2016-04-01)
    Article
    Open Access
    Modern high-performance data centers are responsible for delivering a huge variety of cloud applications to the end-users, which are increasingly pushing the limits of the currently deployed computing and network infrastructure. ...
  • Joint content placement and lightpath routing and spectrum assignment in CDNs over elastic optical network scenarios 

    Perelló Muntan, Jordi; Walkowiak, Krzysztof; Klinkowski, Miroslaw; Spadaro, Salvatore; Careglio, Davide (2016-03-01)
    Article
    Restricted access - publisher's policy
    In this work, we address the problem of jointly deciding the placement of the contents delivered by a Content Distribution Network (CDN) among the available data centers, together with the allocation of the lightpaths ...
  • Resolution of moment equations in a nonlinear optical amplifier 

    Junyent Giralt, Gabriel; Usandizaga Sainz, Aranzazu (Institution of Electrical Engineers, 1987-01-02)
    Article
    Open Access
    In the letter a new method for the resolution of the moment equations in a nonlinear optical amplifier is exposed. Results for the four first moments for the saturated and unsaturated absorption cases are presented. These ...
  • Statistical analysis of nonlinear optical amplifier in high saturation 

    Ruiz Moreno, Sergio; Junyent Giralt, Gabriel; Soneira Ferrando, M. José (1988-02)
    Article

  • Microwave imaging with crossed linear arrays 

    Soneira Ferrando, M. José; de los Reyes, Elías; Bolomey, Jean Charles (1987-11-11)
    Article
    Open Access
    The capabilities of a microwave imaging system working in air using two crossed linear arrays are described. The analytic expressions of the focusing procedures are derived, resolution and available volume of reconstruction ...
