General Gap Analysis for Autonomic Networking
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 background by reviewing the
current status of autonomic aspects of IP networks and the extent to
which current network management depends on centralization and human
administrators. Finally, the document outlines the general features
that are missing from current network abilities and are needed in the
ideal Autonomic Network concept.
This document is a product of the IRTF's Network Management Research
Group.

RFC 7576 Autonomic Networking Gap Analysis June 2015
1. Introduction
The general goals and relevant definitions for Autonomic Networking
are discussed in [RFC7575]. 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
