     Autonomic IPv6 Edge Prefix Management in Large-scale Networks
                 draft-ietf-anima-prefix-management-07

Abstract

   This document defines two autonomic technical objectives for IPv6
   prefix management at the edge of large-scale ISP networks, with an
   extension to support IPv4 prefixes.  An important purpose of the
   document is to use it for validation of the design of various
   components of the autonomic networking infrastructure.
