         CERNET deployment of IVI/MAP-T in an IPv6-only network
                  draft-xli-v6ops-cernet-deployment-02

Abstract

   This document presents the China Education and Research Network
   (CERNET)'s IPv4 as a Service (IPv4aaS) design, deployment and
   operation experience.

   The techniques used are IPv4/IPv6 stateless translation both in the
   forms of single translation (IVI, for IPv6-only servers) and double
   translation (MAP-T, for dual-stack clients).
