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.

   This memo documents the main results of the 8th workshop of the
   Network Management Research Group (NMRG) of the Internet Research
   Task Force (IRTF) hosted by the University of Texas at Austin.
