An Autonomic Control Plane (ACP)
draft-ietf-anima-autonomic-control-plane-12
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 OAM (Operations Administration and
Management) communications over a network that is secure and reliable
even when the network is not configured, or not misconfigured.
