  • Analysis of traffic engineering information dissemination strategies in PCE-based multi-domain optical networks 

    Spadaro, Salvatore; Perelló Muntan, Jordi; Hernández Sola, Guillem; Moreno, A.; Agraz Bujan, Fernando; Comellas Colomé, Jaume; Junyent Giralt, Gabriel (IEEE Computer Society Publications, 2010)
    Conference report
    Open Access
    This paper presents and compares different TE information dissemination strategies between Path Computation Elements (PCEs) in multi-domain optical networks. In such network context, recent studies have found that ...
  • Enhanced domain disjoint backward recursive TE path computation for PCE-based multi-domain networks 

    Hernández Sola, Guillem; Perelló Muntan, Jordi; Agraz Bujan, Fernando; Velasco Esteban, Luis Domingo; Spadaro, Salvatore; Junyent Giralt, Gabriel (2011-04)
    Article

    The ability of computing optimal routes poses new challenges when extending it to larger multi-domain network scenarios, as the quality of these computed endto-end inter-domain routes depends on the selection of the domain ...
  • Network convergence and QoS for future multimedia services in the VISION project 

    Pérez, Luís; Velasco Esteban, Luis Domingo; Rodríguez, Juan; Capelastegui, Pedro; Hernández Sola, Guillem; Calavia, Lorena; Marqués, Antonio; Iribarne, Borja; Pozo, Amador; Poorter, Antoine De (2012)
    Article
    Restricted access - publisher's policy
    The emerging use of real-time 3D-based multimedia applications imposes strict quality of service (QoS) requirements on both access and core networks. These requirements and their impact to provide end-to-end 3D videoconferencing ...
  • Scalable hybrid path computation procedure for PCE-based 

    Hernández Sola, Guillem; Perelló Muntan, Jordi; Agraz Bujan, Fernando; Spadaro, Salvatore; Comellas Colomé, Jaume; Junyent Giralt, Gabriel (2011)
    Conference report
    Restricted access - publisher's policy
    In the Hierarchical Path Computation Element (H-PCE) architecture, an optimum end-to-end path is computed using a hierarchical relationship among PCEs. An H-PCE-based path computation procedure provides low network ...
  • Scalable hybrid path computation procedure for PCE-based multi-domain WSON networks 

    Hernández Sola, Guillem; Perelló Muntan, Jordi; Agraz Bujan, Fernando; Spadaro, Salvatore; Comellas Colomé, Jaume; Junyent Giralt, Gabriel (IEEE, 2011)
