“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

“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.
