Abstract

   This document provides an overview of a workshop held by the Internet
   Architecture Board (IAB) on Network Management.  The workshop was
   hosted by CNRI in Reston, VA, USA on June 4 thru June 6, 2002.  The
   goal of the workshop was to continue the important dialog started
   between network operators and protocol developers, and to guide the
   IETFs focus on future work regarding network management.  This report
   summarizes the discussions and lists the conclusions and
   recommendations to the Internet Engineering Task Force (IETF)
   community.

1. Introduction

   The IETF has started several activities in the operations and
   management area to develop technologies and standards that aim to
   help network operators manage their networks.  The main network
   management technologies currently being developed within the IETF
   are:

   o  The Simple Network Management Protocol (SNMP) [RFC3410] was
      created in the late 1980s.  The initial version (SNMPv1) is widely
      deployed, while the latest version (SNMPv3), which addresses
      security requirements, is just beginning to gain significant
      deployment.

   o  The Common Information Model (CIM) [CIM], developed by the
      Distributed Management Task Force (DMTF), has been extended in
      cooperation with the DMTF to describe high-level policies as rule
      sets (PCIM) [RFC3060].  Mappings of the CIM policy extensions to
      LDAP schemas have been defined and work continues to define
      specific schema extension for QoS and security policies.

   o  The Common Open Policy Service (COPS) [RFC2748] protocol has been
      extended to provision configuration information on devices (COPS-
      PR) [RFC3084].  Work is underway to define data definitions for
      specific services such as Differentiated Services (DiffServ).

RFC 3535            IAB Network Management Workshop             May 2003

   During 2001, several meetings have been organized at various events
   (NANOG-22 May 2001, RIPE-40 October 2001, LISA-XV December 2001,
   IETF-52 December 2001) to start a direct dialog between network
   operators and protocol developers.  During these meetings, several
   operators have expressed their opinion that the developments in the
   IETF do not really address their requirements, especially for
   configuration management.  This naturally leads to the question of
   whether the IETF should refocus resources, and which strategic future
   activities in the operations and management area should be started.

   The Internet Architecture Board (IAB), on June 4 thru June 6, 2002,
   held an invitational workshop on network management.  The goal of the
   workshop was to continue the important dialog started between network
   operators and protocol developers, and to guide the IETFs focus on
