Shepherd writeup
draft-ietf-v6ops-464xlat

Technical Summary:

   This document describes an architecture (464XLAT) for providing
   limited IPv4 connectivity across an IPv6-only network by combining
   existing and well-known stateful protocol translation RFC 6146 in the
   core and stateless protocol translation RFC 6145 at the edge. 464XLAT
   is a simple and scalable technique to quickly deploy limited IPv4
   access service to IPv6-only edge networks without encapsulation.

Working Group Summary:

The working group, for the most part, the working group found this
uncontroversial; it is a way to deploy an IPv6-only core in a mobile network
and use translation to provide access to IPv4 content. The folks working on the
software "MAP" technology objected to it as it is a deployment technology
simpler than MAP and takes shortcuts that may hobble such deployments in the
long term. Rémi Després made suggestions on the list and had some support.
However, the suggested approaches were more "different" than "better", and
neither built consensus nor demonstrated issues requiring changes to the
document.

Document Quality:

The document is a description of how to build a certain service offering. There
are ways to build other service offerings, and they may or may not be better.
However, the service offering described has been implemented and in fact works.
