    • Brokered orchestration for end-to-end service provisioning across heterogeneous multi-operator (Multi-AS) optical networks 

      Castro Casales, Alberto; Velasco Esteban, Luis Domingo; Gifre Renom, Lluís; Chen, Cen; Yin, Jie; Zhu, Zuqing; Proietti, Roberto; Yoo, Sung-Joo Ben (2016-12-01)
      Article
      Open Access
      This paper proposes a new networking paradigm introducing the broker-plane above the management planes of Autonomous Systems (ASes). The brokers communicate with the manager of each AS to assist coordinate end-to-end ...

    • Designing a digital twin for quantum key distribution 

      Ahmadian, Seyed Morteza; Ruiz Ramírez, Marc; Berkay Ön, Mehmet; Singh, Sandeep Kumar; Comellas Colomé, Jaume; Proietti, Roberto; Yoo, Sung-Joo Ben; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference report
      Open Access
      Classical optical devices lack precision when they operate on single photons. We report a Quantum Digital Twin (QDT) to improve Quantum Key Distribution (QKD) implementations. We show a QDT increasing the Key Exchange Rate ...

    • Experimental assessment of degradation - triggered reconfiguration in optically interconnected cloud - RAN 

      Gifre Renom, Lluís; Ruiz Ramírez, Marc; Castro Casales, Alberto; Proietti, Roberto; Yoo, Sung-Joo Ben; Velasco Esteban, Luis Domingo (Optical Society of American (OSA), 2017)
      Conference report

      C-RAN control architecture is proposed and experimentally assessed. A local controller in each location receives latency, jitter, and BER monitoring data from local BBUs and detects a CPRI degradation, which triggers a ...

    • Experimental demonstration of cognitive provisioning and alien wavelength monitoring in multi-domain EON 

      Proietti, Roberto; Chen, Xiaoliang; Castro Casales, Alberto; Liu, Gengchen; Lu, Hongbo; Zhang, Kaiqi; Guo, Jiannan; Zhu, Zuqing; Velasco Esteban, Luis Domingo; Yoo, Sung-Joo Ben (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Open Access
      This paper proposes a cognitive multi-domain EON architecture with machine-learning aided RMSA and alien wavelength monitoring. Testbed experiments show modulation format recognition, QoT monitoring and cognitive routing ...

    • Meeting the requirements to deploy cloud RAN over optical networks 

      Velasco Esteban, Luis Domingo; Castro Casales, Alberto; Asensio Garcia, Adrian; Ruiz Ramírez, Marc; Liu, G.; Qin, C.; Proietti, Roberto; Yoo, Sung-Joo Ben (Optical Society of America, 2017-03-01)
      Article
      Open Access
      Radio access network (RAN) cost savings are expected in future cloud RAN (C-RAN). In contrast to traditional distributed RAN architectures, in C-RAN, remote radio heads (RRHs) from different sites can share baseband ...

    • Soft failure localization during commissioning testing and lightpath operation 

      Pérez Vela, Alba; Shariati, Mohammad Behnam; Ruiz Ramírez, Marc; Cugini, Filippo; Castro Casales, Alberto; Lu, Hongbo; Proietti, Roberto; Comellas Colomé, Jaume; Castoldi, Piero; Yoo, Sung-Joo Ben; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2017-11-09)
      Article
      Open Access
      In elastic optical networks (EONs), effective soft failure localization is of paramount importance to early detection of service level agreement violations while anticipating possible hard failure events. So far, failure ...
