      The recent advances in optical technologies pave the way to the deployment of high-bandwidth services. As reliability becomes a mandatory requirement for some of these services, network providers must endow their networks ...
    • Experimental assessment of ABNO-driven multicast connectivity in flexgrid networks 

      Gifre Renom, Lluís; Paolucci, Francesco; Gonzalez de Dios, Oscar; Velasco Esteban, Luis Domingo; Contreras, Luis Miguel; Cugini, Filippo; Castoldi, Piero; López Álvarez, Victor (2015-01-14)
      Article
      Open Access
      The increasing demand of internet services is pushing cloud services providers to increase the capacity of their data centers (DC) and create DC federations, where two or more cloud providers interconnect their infrastructures. ...
    • 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 ...
    • First experimental assessment of ABNO-driven in-operation flexgrid network re-optimization 

      Gifre Renom, Lluís; Paolucci, Francesco; Velasco Esteban, Luis Domingo; Aguado, Alejandro; Cugini, Filippo; Castoldi, Piero; López Álvarez, Victor (2015-02-01)
      Article
      Open Access
      Traffic affected by link failures can be recovered using path restoration schemes. In dynamically operated networks provided with a control plane, restoration algorithms run in a centralized element, such as the path ...
    • REACTION: Research and experimental assessment of control plane architectures for in-operation flexgrid network re-optimization 

      Cugini, Filippo; Velasco Esteban, Luis Domingo; Gifre Renom, Lluís; Dallaglio, Mateo; López Álvarez, Victor; Fernández Palacios, Juan Pedro (2015)
      External research report
      Open Access
      The REACTION project proposes, designs, and validates flexi-grid elastic optical networks enabling software-controlled high-rate transmissions. In this paper, the main project objectives are reported, together with a brief ...
    • Scalability of telecom cloud architectures for live-TV distribution 

      Asensio Carmona, Adrian; Contreras, Luis Miguel; Ruiz Ramírez, Marc; López Álvarez, Victor; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Conference report
      Restricted access - publisher's policy
      A hierarchical distributed telecom cloud architecture for live-TV distribution exploiting flexgrid networking and SBVTs is proposed. Its scalability is compared to that of a centralized architecture. Cost savings as high ...
    • TelcoFog: A unified flexible fog and cloud computing architecture for 5G networks 

      Vilalta, Ricard; López Álvarez, Victor; Giorgetti, Alessio; Peng, Shuping; Orsini, Vittorio; Velasco Esteban, Luis Domingo; Serral Gracià, René; Morris, Donald; Fina, Silvia de; Cugini, Filippo; Castoldi, Piero; Mayoral, Arturo; Casellas Regi, Ramón; Martínez, Ricardo; Verikoukis, Christos; Ricart Muñoz, Raul (2017-08-01)
      Article
      Open Access
      Telecom operators require cloud computing and storage infrastructures, integrated with their heterogeneous access and transport networks, in order to provide software defined networking (SDN), network functions virtualization ...
    • Towards a network operating system 

      López Álvarez, Victor; Gonzalez de Dios, Oscar; Fuentes, Beatriz; Yannuzzi, Marcelo; Fernández Palacios, Juan Pedro; Lopez, Diego (2014)
      Conference report
      Restricted access - publisher's policy
      A Network Operating System (NetOS) is a novel paradigm for developing a next-generation network management and operation platform. As we shall describe, NetOS not only goes far beyond the SDN concepts but also constitutes ...
    • Virtual network topology adaptability based on data analytics for traffic prediction 

      Morales Alcaide, Fernando; Ruiz Ramírez, Marc; Gifre Renom, Lluís; Contreras Murillo, Luis Miguel; López Álvarez, Victor; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2017-01-26)
      Article
      Open Access
      The introduction of new services requiring large and dynamic bitrate connectivity can cause changes in the direction of the traffic in metro and even core network segments throughout the day. This leads to large overprovisioning ...
