Digital Twin Optical Network as Enhanced Network Operation

This white paper addresses the interoperability requirements for digital twin optical networks as an enhanced network operation that interacts between optical networks and management-control systems. It specifies the relationship between the digital twin optical network and management-control systems, detailing interface operations, input/output data requirements, and data collection. This information is crucial for standardizing digital twin optical networks to enable intelligent control. The document outlines various use cases for digital twin optical networks, including rapid service deployment, performance evaluation and optimization, fault localization and simulation, network planning and simulation, and cutover scheduling and risk assessment. Each use case is presented with specific interactions and data requirements, illustrating the practical applications of digital twin technology in enhancing network operations. The paper aims to promote worldwide compatibility of optical internetworking products and supports the work of national and international standards bodies.
