The following 13 (!) B5G-OPEN works will be presented at the OFC Conference:

#1 Velasco, P. Gonzalez, and M. Ruiz, “An Intelligent Optical Telemetry Architecture” Optical Fiber Communication Conference (OFC), 2023. Abstract: A distributed telemetry system is proposed with agents receiving and analyzing data before sending to a centralized manager. Intelligent data aggregation on optical constellations telemetry largely reduces data rate without introducing significant error.

#2 Istvan Pelle, Francesco Paolucci, Balazs Sonkoly, Filippo Cugini, “P4-based Hitless FaaS Load Balancer for Packet-Optical Network Edge Continuum”, OFC 2023, Th1D.5, Session Time and Dates: March 9, 2023 from 8:00 AM to 10:00 AM EDT. Abstract: P4 and novel node telemetry are leveraged to provide load balancing of ultra- low latency serverless application to multiple edges. Handling the overload of one edge  without observable change in application delay is demonstrated.

#3 Filippo Cugini, Carlos Natalino da Silva, Davide Scano, Francesco Paolucci, Paolo Monti, “P4-based Telemetry Processing for Fast Soft Failure Recovery in Packet-Optical Networks”, OFC 2023, M1G.2,  Session Time and Dates: March 6, 2023 from 8:00 AM to 10:00 AM EDT Abstract: A novel framework for in-network P4 processing of distributed multi-layer telemetry data is presented, enabling effective soft failure detection and recovery strategies enforced in just a few microseconds.

#4 Davide Scano, Jordi Ortiz, Alessio Giorgetti, José Manuel Martínez, Andrea Sgambelluri, Emilio Riccardi, Filippo Cugini, Pablo Pavon, “Hybrid SDN Orchestration in Multi-Layer Network with SONiC Packet-Optical Nodes and Coherent Pluggables”, OFC 2023, M3Z.13, Session Time and Dates: March 6, 2023 from 2:00 PM to 4:15 PM EDT  Abstract: This demo presents a comprehensive framework exploiting effective cooperation of packet-optical nodes, at the edge of packet and optical domains, managed by the BGP and OSPF protocols and a Hierarchical Control Architecture. The framework enables orchestrated provisioning and soft failure recovery across a multi-layer metro network.

#5 Gonzalez, R. Casellas, J-J Pedreno-Manresa, A. Autenrieth, F. Boitier, B. Shariati, J. Fischer, M. Ruiz, J. Comellas, and L. Velasco, “Distributed Architecture Supporting Intelligent Optical Measurement Aggregation and Streaming Event Telemetry“, Optical Fiber Communication Conference (OFC), 2023. Abstract: A distributed telemetry system integrating optical measurement and event data collection is demonstrated. Measurements of optical spectra from Nokia Bell Labs, of optical transponders from ADVA and SDN controller events from CTTC will be showcased.

#6 Devigili, M. Ruiz, S. Barzegar, N. Costa, A. Napoli, J. Pedro, and L. Velasco, “Degradation Detection and Severity Estimation by Exploiting an Optical Time and Frequency Digital TwinOptical Fiber Communication Conference (OFC), 2023. Abstract: We exploit the intrinsic advantages of a time and frequency domain digital twin to detect degradations and to estimate their severity. Noticeable performance shown for filter failures confirms the usefulness of this approach.

#7 Nadal, R. Casellas, J. M. Fàbrega, F. J. Vílchez and M. Svaluto Moreolo “Enabling Multiband Transmission and Programmability in Disaggregated Optical Metro Networks”, Optical Fiber Communication Conference (OFC), 2023. Abstract: A multi band (MB) sliceable bandwidth/bit rate variable (S-BVT) architecture is experimentally assessed over a disaggregated optical metro network. The programmability of the MB S-BVT is demonstrated by the implementation of an OpenConfig SDN agent.

#8 Hernández-Chulde, R. Casellas, R. Martínez, R. Vilalta, R. Muñoz, “DRL for VNF placement in Inter-Data Center Elastic Optical Networks“. Abstract: A novel DRL solution for service provisioning over a cloud/EON stratum is presented. The benefit of DRL is that it can be adopted in different (unseen) EON topologies attaining better service blocking compared to traditional heuristics.

#9 Lareb Zar Khan, Pedro J. Freire, Joao Pedro, Nelson Costa, Antonio Napoli, Nicola Sambo, “Data Augmentation to Reduce Computational Complexity of Neural-Network-Based Soft-Failure Cause Identifier”, Optical Fiber Communication Conference (OFC), 2023.  
#10 Mohammad M. Hosseini, Joao Pedro, Nelson Costa, Antonio Napoli, Jaroslaw E. Prilepsky, Sergei K. Turitsyn , “Optimal Design of Filterless Horseshoe Networks Supporting Point-to-Multipoint Transceivers”, Optical Fiber Communication Conference (OFC), 2023. 
#11 J. A. Hernandez, F. Arpanaei, G. Martinez, O. Gonzalez de Dios, J. P. Fernandez-Palacios, A. Napoli, “Clustering-based dynamic bandwidth allocation for point-to-multipoint coherent optics”, Optical Fiber Communication Conference (OFC), 2023.  
#12 M. A. Iqbal, P. Wright, A. Lord, “Technical Study on the Viability of Hollow-Core and Ultra-low-loss Silica Fibres in Metro-Core Optical Network”, Optical Fiber Communication Conference (OFC), 2023.  
#13 André Souza, António Eira, Nelson Costa, João Pedro, João Pires, “On the Impact of Fault-Induced Power Transients in Wideband Optical Networks”, Optical Fiber Communication Conference (OFC), 2023.
