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
