General Gap Analysis for Autonomic Networking
draft-irtf-nmrg-an-gap-analysis-04
Abstract
This document provides a problem statement and general gap analysis
for an IP-based autonomic network that is mainly based on distributed
network devices. The document provides a background by reviewing the
current status of autonomic aspects of IP networks and the extent to
which current network management depends on centralisation and human
administrators. Finally the document outlines the general features
missing from current network abilities that are needed in the ideal
autonomic network concept.
