scope:

This Recommendation describes roles, a role-based model, and service scenarios in quantum key distribution networks (QKDN) from different deployment and operation perspectives. This Recommendation identifies various models that require security application services with QKDN and exiting user networks.

This Recommendation can be used as a guideline for applying service scenarios that globally utilize QKDN from a role point of view as well as for deployment and operation of QKDN from a telecom operators' point of view in an international context.

This Recommendation does not identify, in an exhaustive manner, all roles, a role-based model and service scenarios of QKDN.
