Deliverable D4.2: Optical systems enabling ultra-high-capacity access-metro networks
This deliverable reports an updated design and implementation of the SEASON control plane, presenting the latest results of WP4 across monitoring and telemetry, single- and multi-domain control, and AI/ML-based self-management. Its primary goal is to identify and characterize the key functional components of the SEASON control plane, clearly defining their roles, responsibilities, and interfaces enabling interworking across systems, with a focus on integration for WP5 demonstrations.
The report first consolidates the SEASON control plane architecture, refining and clarifying interworking and interfaces compared to the initial design in D4.1. A validated list of control-plane elements is provided to support system integration activities.
It then details the control and configuration of the optical data plane, structured around four main building blocks.
First, it presents SDN agents deployed alongside data-plane devices, responsible for translating high-level controller instructions into hardware-specific configurations. These include agents for DPUs, IPoWDM scenarios with pluggables, a multiband SDM node prototype, and a FlexTelemetry agent.
Second, it describes the per-domain SDN controllers and associated use cases, covering optical line systems over ROADM networks, multiband SDM transport, OpenXR point-to-multipoint pluggables, SDM-PON access networks, and integration with the RAN via the RAN Intelligent Controller (RIC).
Third, it addresses multi-domain and service-level control, enabling end-to-end orchestration across heterogeneous domains.
Finally, it introduces operational, planning, and resource allocation tools supporting network management.
As part of the closed-loop control framework for autonomous networking, the deliverable also examines the telemetry systems adopted in SEASON and their role in advanced use cases, including digital twin operation, energy efficiency optimization, and the application of DevOps principles to network control and management.
