Abstract

There has been ongoing confusion about the differences between Information Models and Data Models for defining managed objects in network management. This document explains the differences between these terms by analyzing how existing network management model specifications (from the IETF and other bodies such as the International Telecommunication Union (ITU) or the Distributed Management Task Force (DMTF)) fit into the universe of Information Models and Data Models.

1. Introduction

   Currently multiple languages exist to define managed objects.

   Examples of such languages are the Structure of Management

   Information (SMI) [1], the Structure of Policy Provisioning

   Information (SPPI) [2] and, within the DMTF, the Managed Object

   Format (MOF) [3].  Despite the fact that multiple languages exist, a
