“Deep Learning -based Real-Time Analysis of Lightpath Optical Constellations [Invited],” by Ruiz, D. Sequeira, and L. Velasco, IEEE/OPTICA Journal of Optical Communications and Networking (JOCN), vol. 14, pp. C70-C81, 2022. In-phase (I) and quadrature (Q) constellation analysis enables deep understanding of the characteristics of lightpaths. We present methods based on deep learning. https://opg.optica.org/jocn/abstract.cfm?uri=jocn-14-6-C70
“On the Benefits of Point-to-Multipoint Coherent Optics for Multilayer Capacity Planning in Ring Networks with Varying Traffic Profiles” by P. Pavon-Marino, N. Skorin-kapov, M. V. Bueno-Delgado, J. Back, and A. Napoli Abstract: Point-to-Multipoint (P2MP) coherent optics using Digital Subcarrier Multiplexing (DSCM) have recently been proposed as a promising new technology to reduce the cost and complexity of optical transport networks,particularly those in metro aggregation scenarios with Hub-and-Spoke (H&S) traffic patterns
“SDN-enabled Multi-band S-BVT within Disaggregated Optical Networks”, by L. Nadal, M. Svaluto Moreolo, J. M. Fàbrega, F. J. Vílchez. Abstract: A novel open SDN-enabled multi-band S-BVT based on multi-carrier modulation and direct detection receiver configuration is experimentally validated over up to 50.47 km of SSMF, enabling C-, L- and S-band transmission in disaggregated optical metro networks.

“QoT-Driven Optical Control and Data Plane in Multi-Vendor Disaggregated Networks” by G.Borraccini, S. Straullu, A. Giorgetti, R. D’Ingillo, D. Scano, A. D’Amico, E. Virgillito, A. Nespola, N. Sambo, F. Cugini, V. Curri Abstract: A novel disaggregated network architecture with independent PCE and optical control based on GNPy is proposed and experimentally validated over a network including two independent OLSs for total 1400 km, ROADM whiteboxes and pluggable transceivers.
“Applications of P4-based Network Programmability in Optical Networks” by F. Cugini, D. Scano, A. Giorgetti, A. Sgambelluri, F. Paolucci, J.J. Vegas Olmos, P. Castoldi Abstract: This paper presents potentials and challenges of disaggregated metro-edge networking based on open packet-optical nodes encompassing coherent pluggable modules, SONiC open operating system, and P4-based packet switching programmability.
“Evaluation of Deep Reinforcement Learning for Restoration in Optical Networks” By C. Hern´andez-Chulde, R. Casellas, R. Mart´ınez, R. Vilalta, R. Munoz – CTTC. Abstract: A deep reinforcement learning-based agent is presented to perform autonomous lightpath restoration upon a link failure event. The agent is evaluated against other heuristic algorithms under different trafﬁc load and failure duration scenarios.
“An SDN control plane for multiband networks exploiting a PLI-aware routing engine” by Ramon Casellas, Evangelos Kosmatos, Andrew Lord, Chris Matrakidis, Ricardo Martínez, Dimitris Uzunidis, Ricard Vilalta, Alexandros Stavdas, Raül Muñoz – CTTC, OpenLightComm Europe, British Telecom. Abstract: We report the design of a TAPI SDN control plane for multi-band networks with externalized PLI-aware RMSA. We detail the architecture, data model extensions, algorithms and the implementation and validation in an
