    • 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 ...
    • 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
      Restricted access - publisher's policy
      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 ...
    • Experimental demonstration of heterogeneous cross stratum broker for scientific applications 

      Castro Casales, Alberto; Pérez Vela, Alba; Gifre Renom, Lluís; Proietti, Roberto; Cen, Chen; Yin, J.; Chen, Xiaoliang; Cao, Zheng; Zhu, Zuqing; Mishra, Vinod; Velasco Esteban, Luis Domingo; Yoo, S. J. B. (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Conference report
      Restricted access - publisher's policy
      We propose and demonstrate cross-stratum Broker orchestration for scientific applications and heterogeneous resources reservation in DCs, HPC facilities and networks belonging to different operators. Experiments were ...
    • Experimental demonstration of machine-learning-aided QoT estimation in multi-domain elastic optical networks with alien wavelengths 

      Proietti, Roberto; Chen, Xiaoliang; Zhang, Kaiqi; Liu, Gengchen; Shamsabardeh, Mohammadsadegh; Castro, Alberto; Velasco Esteban, Luis Domingo; Zhu, Zuqing; Yoo, S.J. Ben (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Article
      Open Access
      In multi-domain elastic optical networks with alien wavelengths, each domain needs to consider intradomain and interdomain alien traffic to estimate and guarantee the required quality of transmission (QoT) for each lightpath ...
    • 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; Behnam Shariati, Mohammad; 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 ...
