                       An Autonomic Control Plane
              draft-ietf-anima-autonomic-control-plane-01

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 an "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 communications
   over a network that is not configured, or mis-configured.
