    Telecom operators’ infrastructure is undergoing high pressure to keep the pace with the traffic demand generated by the societal need of remote communications, bandwidth-hungry applications, and the fulfilment of 5G requirements. Software-defined networking (SDN) entered in scene decoupling the data-plane forwarding actions from the control-plane decisions, hence boosting network programmability and innovation. Optical networks are also capitalizing on SDN benefits jointly with a disaggregation trend that holds the promise of overcoming traditional vendor-locked island limitations. In this work, we present our framework for disaggregated optical networks that leverages on SDN and container-based management for a realistic emulation of deployment scenarios. Our proposal relies on Kubernetes for the containers’ control and management, while employing the NETCONF protocol for the interaction with the light-weight software entities, i.e., agents, which govern the emulated optical devices. Remarkably, our agents’ structure relies on components that offer high versatility for accommodating the wide variety of components and systems in the optical domain. We showcase our proposal with the emulation of an 18-node European topology employing Cassini-compliant optical models, i.e., a state-of-the-art optical transponder proposed in the Telecom Infrastructure Project. The combination of our versatile framework based on containerized entities, the automatic creation of agents and the optical-layer characteristics represents a novel approach suitable for operationally complex carrier-grade transport infrastructure with SDN-based disaggregated optical systems.This research was funded Spanish Government: ONOFRE-2 project under Grant TEC2017-84423-C3-2-P (MINECO/AEI/FEDER, UE) and the Go2Edge project under Grant RED2018-102585-T; and by the European Commission: METRO-HAUL project (G.A. 761727)

    Este trabajo consiste en el desarrollo una plataforma web de código abierto de evaluación de competencias y habilidades, creación de itinerarios de aprendizaje, búsqueda de empleo y cursos de formación centrada en el sector de la madera y mueble. Esta herramienta dispone de tres perfiles de usuario en un único sistema: usuario que busca empleo y/o cursos de formación, proveedor de empleo (reclutador o empresa), y proveedor de recursos de aprendizaje. Estos tres usuarios interactúan entre sí de manera que los usuarios buscan ofertas de trabajo de las empresas y cursos de formación de los proveedores, las empresas buscan candidatos para sus ofertas de empleo y cursos de formación para sus empleados, y los proveedores de formación buscan las habilidades más demandadas por las empresas para elaborar sus recursos. La herramienta utiliza machine learning para ofrecer, mediante algoritmos de recomendación, resultados personalizados basados en usuarios similares. Esta plataforma web ha sido financiada por el proyecto europeo ALLVIEW (Alliance of Centres of Vocational Excellence in the Furniture and Wood sector [1]), donde la UPCT es partícipe del proyecto.Palabras clave Desarrollo web, arquitecturas web, ESCO, evaluación de habilidades, sistemas de recomendación.Escuela Técnica Superior de Ingeniería de TelecomunicaciónUniversidad Politécnica de Cartagen
