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.
