    • Autonomic NFV network services on top of disaggregated optical metro networks 

      Esmenats, P. R.; Casellas Regi, Ramon; Gifre Renom, Lluís; Pérez Vela, Alba; Ruiz Ramírez, Marc; Martínez, Ricardo; Velasco Esteban, Luis Domingo (2019)
      Conference report
      Restricted access - publisher's policy
      Control and orchestration of metro network to support dynamic provisioning and reconfiguration of services based on Virtual Network Functions are demonstrated through a CDN example. Interaction among CASTOR MDA, OSM and ...
    • Demonstration of monitoring and data analytics-triggered reconfiguration in partially disaggregated optical networks 

      Gifré Renom, Lluís; Boitier, Fabien; Delezoide, Camille; Ruiz Ramírez, Marc; Buffa, Marta; Morea, Annalisa; Casellas Regi, Ramon; Velasco Esteban, Luis Domingo; Layec, Patricia (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Open Access
      We demonstrate a novel agent for optical disaggregated optical networks. When the Monitoring and Data Analytics detects a degradation, it recommends the SDN controller to trigger a network reconfiguration computed by a ...
    • Design and assessment of FM-MCFs-suited SDM-ROADMs with versatile spatial group configurations and unified QoT estimator 

      Rumipamba Zambrano, Rubén Darío; Muñoz González, Raül; Casellas Regi, Ramon; Perelló Muntan, Jordi; Spadaro, Salvatore; Elfiqi, Abdulaziz E. (Institute of Electrical and Electronics Engineers (IEEE), 2020-11-15)
      Article
      Open Access
      In this article, we focus on the design of different node architectures suitable for few-mode multi-core fibers (FMMCFs) based networks. Both dimensions, core and mode, open different possible ways to group spatial channels ...
    • Monitoring and data analytics-triggered reconfiguration in partially disaggregated optical networks 

      Gifré Renom, Lluís; Boitier, Fabien; Delezoide, Camille; Ruiz Ramírez, Marc; Buffa, Marta; Morea, Annalisa; Casellas Regi, Ramon; Velasco Esteban, Luis Domingo; Layec, Patricia (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Open Access
      We present ADONIS, which stands for Aggregator/Disaggregator for Optical Network equIpmentS, a novel open device agent able to construct logical network devices from (dis)aggregation of physical components in order to ...
    • The dichotomy of distributed and centralized control: METRO-HAUL, when control planes collide for 5G networks 

      King, Daniel; Farrel, Adrian; King, Emiko Nishida; Casellas Regi, Ramon; Velasco Esteban, Luis Domingo; Nejabati, Reza; Lord, Andrew (2019-07)
      Article
      Open Access
      Automating the provisioning of 5G services, deployed over a heterogeneous infrastructure (in terms of domains, technologies, and management platforms), remains a complex task, yet driven by the constant need to provide ...
    • Towards an SDN/NFV-based multi-tenant network and cloud testbed for end-to-end 5G services 

      Muñoz González, Raül; Mangues Bafalluy, Josep; Bartzoudis, Nikolaos; Vilalta Cañellas, Ricard; Martínez Rivera, Ricardo Victor; Casellas Regi, Ramon; Baldo, Nicola; Núñez Martínez, José; Requena Esteso, Manuel; Font Bach, Oriol; Payaró Llisterri, Miquel; Henarejos Hernández, Pol; Pérez Neira, Ana Isabel (Wireless World Research Forum (WWRF), 2015)
      Conference report
      Open Access
      5G has a main requirement of highly flexible, ultralow latency and ultra-high bandwidth virtualized infrastructure in order to deliver end-to-end services. This requirement can be met by efficiently ...
