scope:

The present document defines and describes the reference architecture for the end-to-end Zero-touch network and Service Management (ZSM) framework based on a set of user scenarios and requirements documented in ETSI GS ZSM 001 [i.9].

The reference architecture employs a set of architectural principles, described further in the present document, and a service-centric architectural model to define at a high level a set of management services for zero-touch network and service management. It also defines means of management service integration, communication, interoperation, and organization. Procedures and detailed information models are beyond the scope of the present document.

The reference architecture also defines normative provisions for externally visible management services, defined as part of the reference architecture, as well as recommendations for their organization. It is assumed that the architectural patterns introduced in the present document can be used not only for the ZSM framework, but also for architecture and design of individual management services.
