          An Overview of the IETF Network Management Standards

Abstract

   This document gives an overview of the IETF network management
   standards and summarizes existing and ongoing development of IETF
   Standards Track network management protocols and data models.  The
   document refers to other overview documents, where they exist and
   classifies the standards for easy orientation.  The purpose of this
   document is, on the one hand, to help system developers and users to
   select appropriate standard management protocols and data models to
   address relevant management needs.  On the other hand, the document
   can be used as an overview and guideline by other Standard
   Development Organizations or bodies planning to use IETF management
   technologies and data models.  This document does not cover
   Operations, Administration, and Maintenance (OAM) technologies on the
   data-path, e.g., OAM of tunnels, MPLS Transport Profile (MPLS-TP)
   OAM, and pseudowire as well as the corresponding management models.
