                 Gap Analysis for Autonomic Networking
                   draft-irtf-nmrg-an-gap-analysis-00

Abstract

   This document summarises a problem statement for an IP-based
   autonomic network that is mainly based on distributed network
   devices.  The document reviews the history and current status of
   autonomic aspects of IP networks.  It then reviews the current
   network management style, which is still heavily depending on human
   administrators.  Finally the document describes the general gaps
   between the ideal autonomic network concept and the current network
   abilities.

1.  Introduction

   The general goals and relevant definitions for autonomic networking
   are discussed in [I-D.irtf-nmrg-autonomic-network-definitions].  In
   summary, the fundamental goal of an autonomic network is self-
   management, including self-configuration, self-optimization, self-
   healing and self-protection.  Whereas interior gateway routing
   protocols such as OSPF and IS-IS largely exhibit these properties,
   most other aspects of networking require top-down configuration often
