  A Framework for Automating Service and Network Management with YANG
            draft-ietf-opsawg-model-automation-framework-03

Abstract

   Data models for service and network management provides a
   programmatic approach for representing services or networks and
   deriving (1) configuration information that will be communicated to
   network and service components that are used to build and deliver the
   service and (2) state information that will be monitored and tracked.
   Indeed, data models can be used during various phases of the service
   and network management life cycle, such as service instantiation,
   provisioning, optimization, monitoring, diagnostic, and assurance.
   Also, data models are instrumental in the automation of network
   management.  They also provide closed-loop control for the sake of
   adaptive and deterministic service creation, delivery, and
   maintenance.

   This document describes an architecture for service and network
   management automation that takes advantage of YANG modeling
   technologies.  This architecture is drawn from a network provider
   perspective irrespective of the origin of a data module; it can thus
   accommodate modules that are developed outside the IETF.

   The document aims in particular to exemplify an approach that
   specifies the journey from technology-agnostic services to
   technology-specific actions.
