ITU-T Y.3811 (09/2022)

Quantum key distribution networks – Functional architecture for quality of service assurance

Recommendation ITU-T Y.3811 specifies the functional architecture of quality of service (QoS) assurance for the quantum key distribution networks (QKDNs).
This Recommendation first provides an overview of the functional architecture of QoS assurance for the QKDN. It then describes the functional architecture of QoS assurance which includes functional entities such as QoS data collection, data processing, data storage, data analytics, QoS anomaly detection and prediction, QoS policy decision making, and enforcement and reporting. Based on the functional entities described in the functional architecture, this Recommendation specifies a basic operational procedure of QoS assurance for the QKDN.
