Summary:
|
ITU-T has approved a series of QKDN related Recommendations, which consider the single-node service model where a user node is supplied with keys by a single QKD node and focus on maximizing the service provision capability of the single QKD node. In practical applications, it can be exceedingly challenging for a single QKD node to handle highly concurrent key supply requests while maintaining an acceptable service-level.
This Supplement considers the multi-point coordination in QKDN, also called QKDNmc. This is a service model where two or more QKD nodes are associated with a user node and coordinated by QKDN to provide superior key supply service. It aims to further improve the service provision capability and resource utilization of the QKDN and can be seen as the supplement and enhancement to these Recommendations.
Focusing on QKDNmc, this Supplement presents an overview and relevant use cases.
