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. Remi Despres 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.
Personnel:
The document shepherd is Fred Baker. The area director is Ron Bonica.
