An Autonomic Control Plane (ACP)
draft-ietf-anima-autonomic-control-plane-20
Abstract
Autonomic functions need a control plane to communicate, which
depends on some addressing and routing. This Autonomic Management
and 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.
