Innovative programmable MBoSDM sliceable bandwidth\/bit rate variable transceiver (S-BVT) and advanced switching solutions supporting C+S+L-bands and multi-core\/fiber operation have been implemented. Two different node prototypes have been developed leveraging wavelength division multiplexing (WDM), MB and SDM technologies depending on the target network segment. The proposed MBoSDM infrastructure increases the overall network capacity, by exploiting spatial channels and multiple transmission bands beyond the C-band, with special focus on efficiency. On top of that, transceiver and node reconfiguration are enabled by the implementation of software-defined network (SDN) control plane by means of SDN agents.\nThe SDN control plane includes a controller that implements YANG models specifically defined for the control of the optical infrastructure. The node agents provide access to data plane programmability, as well as to telemetry data, thus creating a distributed telemetry system able to process large data amounts collected at a high rate. Measurements can be processed locally inside the agents to reduce the data dimensionality and sent to a centralized AI\/ML-based operation system that includes a MB network digital twin (NDT), which provides accurate estimation of the Quality of Transmission (QoT) before optical connections are established (i.e., during the provisioning phase). During optical connection operation, the NDT uses telemetry to fine tune the connection AI\/ML models, which increases the sensibility to any deviation between models'\u2019 estimation and real measurements. This enables detection of QoT degradation and localization of causes.","references":"- SEASON deliverable D3.1, \"\u02dcEnd-to-end design of next generation smart optical networks', D3.2, \"\u02dcOptical systems enabling ultra-high-capacity access\/metro networks', D4.2, \"\u02dcSelf-Managed Sustainable High-Capacity Optical Networks', D4.1, \"\u02dcFirst design and implementation of control plane infrastructure' and D5.1,' Report on the integration and functional validation of integrated SEASON 1.0 solution'. \n- M.
