    • 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 ...
    • Introduction to the ONDM2020 special issue 

      Casellas Regi, Ramon; Muñoz, Raul; Furdek, Marija; Spadaro, Salvatore; Zhu, Zuqing (Institute of Electrical and Electronics Engineers (IEEE), 2021-06-01)
      Article
      Open Access
      This JOCN special issue includes extended versions of selected papers that were presented at the 24th International Conference on Optical Network Design and Modeling (ONDM2020), which took place virtually on May 18–21, ...
    • 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 ...
