IG1253C Intent Life Cycle Management and Interface v1.1.0

This document defines the details of the intent life cycle including the related roles and tasks of intent management functions. Furthermore, this document defines the interface through which these intent managers perform intent life cycle management actions. It proposes the mandatory interface procedures that allow basic intent management. Furthermore, it describes optional procedures that introduce more sophisticated handshake and interaction between intent managers for reaching better results. On the other hand these procedures require more demanding implementations with predictive capabilities.
