   Framework for Automating Service and Network Management with YANG
           draft-wu-model-driven-management-virtualization-03

Abstract

   Model driven service and network management provides a programmatic
   and standards-based way of representing virtual services or networks
   and configuration to the network device that are used to construct
   the service.  It can be used at various phases of service and network
   management life cycle such as service instantiation, service
   provision, optimization, monitoring, and diagnostic.  Also, it can be
   designed to automate network management and provide closed-loop
   control for the sake of agile service creation, delivery and
   maintenance.

   This document provides a framework that describes and discusses an
   architecture for service and network management automation with YANG
   Modeling technologies.  An applicability of YANG data model to
   automation of virtualized network service is also investigated.
