 An Architecture for Data Model Driven Network Management: the Network
                          Virtualization Case
           draft-wu-model-driven-management-virtualization-01

Abstract

   Data Model driven network management 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 provide closed-loop control
   for the sake of agile service creation, delivery and maintenance.

   This document describes an architecture for data model driven network
   management with a sample applicability case: network virtualization
   environments.
