scope:

The present document describes enablers for Closed-Loop Automation (CLA) based on the ZSM architectural framework. The present document initially specifies Closed Loop-specific requirements and introduces Closed Loops within the ZSM framework, from both functional and deployment perspectives. The specifications include enablers for Closed Loop Governance (CLG), covering the definitions of Closed Loop lifecycle management as well as Closed Loop models. Such enablers allow automatic deployment and configuration of Closed Loops involving both the end-to-end service management domain and the individual management domains. Then, the present document specifies enablers for Closed Loops coordination within the ZSM framework, including means for delegation and escalation between Closed Loops as well as other coordination means. Finally, the deliverable specifies stage-2 generic enablers for Closed-Loop Automation (CLA) and includes new management services in addition to those identified in ETSI GS ZSM 002 [2]. Closed loops running entirely within the managed entities are out-of-scope.
