  • An interoperable GMPLS/OBS Control Plane: RSVP and OSPF extensions proposal 

    Pedroso, Pedro; Careglio, Davide; Casellas, Ramon; Klinkowski, Miroslaw; Solé Pareta, Josep (E. Leitgeb, W. Kogler, Z. Ghassemlooy, 2008-07-31)
    Conference report
    Open Access
    The GMPLS/OBS Control Plane is a bold research topic. Optical Burst Switching (OBS) networks need to be capable to be rapidly reconfigured with the aim of achieving an efficient use of bandwidth, low latency and high ...
  • Experimental evaluation of a full-meshed domain abstraction design model for reduced state information dissemination in multi-domain PCE-based WSONs 

    Pagès, Albert; Casellas, Ramon; Perelló Muntan, Jordi; Martínez, Ricardo; Spadaro, Salvatore; Muñoz, Raul (2011)

    A novel full-meshed domain abstraction model for scalable state information in PCEbased WSONs is presented. We experimentally evaluate the state information update reduction and the blocking improvement with regard to a ...
  • Experimental study on the impact of regenerator placement strategies when dynamically provisioning in translucent GMPLS WSON networks 

    Martínez, Ricardo; Casellas, Ramon; Muñoz, Raul; García Manrubia, Bélen; Pavón Mariño, Pablo; Klinkowski, Miroslaw; Careglio, Davide (Optical Society of America, 2011)
    Conference report
    Open Access
    The impact of the regenerator placement strategies when dynamically provisioning connections in translucent WSON is studied. The evaluation is experimentally conducted in the ADRENALINE testbed in terms of the connection ...
  • Experimental validation of end-to-end GMPLS-enabled restoration in multi-domain transparent WSON 

    Martínez, Ricardo; Casellas, Ramon; Velasco Esteban, Luis Domingo; Agraz Bujan, Fernando; Muñoz, Raul; Spadaro, Salvatore (IEEE Computer Society Publications, 2010)
    Conference report
    Open Access
    Two GMPLS restoration strategies operating at wavelength and link granularities are experimentally validated in a multi-domain WSON. The strategies are qualitatively compared in terms of resource usage, restorability and ...
  • GMPLS-based multidomain restoration: analysis, strategies, policies and experimental assessment 

    Velasco Esteban, Luis Domingo; Agraz Bujan, Fernando; Martínez, Ricardo; Casellas, Ramon; Spadaro, Salvatore; Muñoz, Raul; Junyent Giralt, Gabriel (IEEE Press. Institute of Electrical and Electronics Engineers, 2010-07-01)
    Article

    A connection spanning, for example, several countries crosses multiple optical backbone networks, each one controlled by different administrators or operators. In this context, the interworking of these networks is thus ...
  • Improving IA-RWA algorithms in translucent networks by regenerator allocation 

    Marín Tordera, Eva; Martinez, R; Muñoz, R; Casellas, Ramon; Solé Pareta, Josep (IEEE, 2009)
    Conference report
    Open Access
    In this paper we present the impact of considering regenerator allocation when selecting routes and wavelengths in translucent networks. In the regular operation of translucent networks, i.e. with dynamic traffic, we assume ...
  • Regenerator allocation in translucent networks under inaccurate physical information 

    Marín Tordera, Eva; Yannuzzi, Marcelo; Masip Bruin, Xavier; Sánchez López, Sergio; Martínez, Ricardo; Muñoz, Raul; Casellas, Ramon (2009-12-14)
    Conference report
    Open Access
    Optimized regenerator allocation techniques select which of the already installed regenerators in a translucent network must be used in order to maximize the quality of the optical signal while minimizing the opaqueness ...
  • The Effects of Optimized Regenerator Allocation in Trans-lucent Networks under Inaccurate Physical information 

    Marín Tordera, Eva; Yannuzzi, Marcelo; Masip Bruin, Xavier; Sánchez López, Sergio; Martínez, Ricardo; Muñoz, Raul; Casellas, Ramon; Maier, Guido (2010-02-04)
    Conference lecture
