TL;DR: This work details the strategies adopted in the European research project IDEALIST to overcome the predicted data plane capacity crunch in optical networks and highlights the novelties stemming from the flex-grid concept.

TL;DR: This paper identifies the key building blocks for enabling elastic optical networks to provide desired performance improvements over static optical networks, and examines the design of elastic transponders capable of data rate adaptation, interfaces between client packet devices and transponderers supporting flexible traffic aggregation, and associated algorithms for traffic grooming and routing.

TL;DR: The emerging requirements for optical network management automation, the capabilities of current optical systems, and the development and standardization status of data models and protocols are reviewed to facilitate automated network monitoring are reviewed.

TL;DR: An ML-based algorithm life cycle is proposed to facilitate ML deployment in real operator networks and different approaches are analyzed and evaluated for a use case of autonomic transmission, where results show the significant benefits of collective learning.

TL;DR: The ORCHESTRA network makes use of coherent optical transponders as software-defined optical performance monitors (soft-OPMs) to improve the optical network observability and closes the observe–decide–act control loop, automating the mechanisms required to trade efficiency for reliability.
