    Article
    Open Access
    To reap its full benefits, 5G must evolve into a scalable decentralized architecture by exploiting intelligence ubiquitously and securely across different technologies, network layers, and segments. In this article, we ...
  • Intent-based networking and its application to optical networks [invited tutorial] 

    Velasco Esteban, Luis Domingo; Barzegar, Sima; Tabatabaeimehr, Fatemehsadat; Ruiz Ramírez, Marc (2022-01-01)
    Article
    Restricted access - publisher's policy
    The intent-based networking (IBN) paradigm targets defining high-level abstractions so network operators can define what their desired outcomes are without specifying how they would be achieved. The latter can be achieved ...
  • Packet flow capacity autonomous operation based on reinforcement learning 

    Barzegar, Sima; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo (Multidisciplinary Digital Publishing Institute (MDPI), 2021-12-12)
    Article
    Open Access
    As the dynamicity of the traffic increases, the need for self-network operation becomes more evident. One of the solutions that might bring cost savings to network operators is the dynamic capacity management of large ...
