                    An Autonomic Control Plane (ACP)
              draft-ietf-anima-autonomic-control-plane-30

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.
