Summary

Recommendation ITU-T Y.3816 specifies functional architecture enhancement of quality of service (QoS) assurance based on machine learning (ML) for quantum key distribution networks (QKDNs).

Recommendation ITU-T Y.3816 first provides an overview of functional architecture enhancement of ML-based QoS assurance for QKDNs. It then describes a functional architecture enhancement of QoS assurance that includes functional components such as QoS data collection, data processing, data storage, data analytics, QoS anomaly detection and prediction, QoS policy decision making, enforcement and reporting. Based on the capabilities described in the functional architecture enhancement, Recommendation ITU-T Y.3816 specifies an operational procedure of QoS assurance for QKDNs.
