An Autonomic Control Plane (ACP)
draft-ietf-anima-autonomic-control-plane-27
Abstract
Autonomic functions need a control plane to communicate, which
depends on some addressing and routing. This Autonomic Control Plane
should ideally be self-managing, and as independent as possible of
configuration. This document defines such a plane and calls it the
"Autonomic Control Plane", with the primary use as a control plane
for autonomic functions. It also serves as a "virtual out-of-band
channel" for Operations, Administration and Management (OAM)
communications over a network that provides automatically configured
hop-by-hop authenticated and encrypted communications via
automatically configured IPv6 even when the network is not
configured, or misconfigured.
