Summary

Recommendation ITU-T Y.3800 specifies an overview on networks supporting quantum key distribution (QKD). For the purpose of design, deployment, operation and maintenance to support QKD network (QKDN) implementation, the required quality level of quantum key distribution service should be identified and quantified.

Recommendation ITU-T Y.3806 describes high-level and functional quality of service (QoS) requirements for QKDN.

Recommendation ITU-T Y.3807 describes QoS and network performance (NP) on QKDN and specifies the associated relative parameters for QoS and their definitions.

This Recommendation helps to quantify what kind of QoS requirements should be monitored and measured for this purpose; QoS parameters.
