Summary:
|
This Recommendation specifies the requirements for QoS assurance in QKDN resilience. It focuses on standardizing the application of QoS demands to QKDN resilience, ensuring the mechanisms for QKDN resilience support consistent service-level performance during both normal operations and failure conditions, while aligning with broader QoS assurance objectives.
By building upon the resilience models specified in Y.3815 and the QoS demands outlined in Y.3806, this Recommendation bridges the gap between general QoS frameworks and the specific demands of resilience in QKDNs. It addresses the requirements for ensuring resilience with minimal disruption to key supply and defines the necessary conditions for seamless key supply during and after failures.
