Simplified NAT-PT

[Hiroshi MIYATA <miyata@tahi.org>]

Hi All,

I submitted this document.

In this document, I intended to simplify old NAT-PT.
It is not yet completed, but I submitted it to introduce the simple
translator solution in my mind.
My another ID <draft-miyata-v6ops-trans-approach-00.txt>.
It was not concrete enough and there were few discussion on it.
This "sNAT-PT" is aiming to introduce concrete image of
"Current translator model description"in <draft-miyata-v6ops-trans- 
approach-00.txt>.

We have not yet concluded how to work on translator, but I submitted
it to make such discussion smoother.

--------------------------------------

A new version of I-D, draft-miyata-v6ops-snatpt-00.txt has been
successfuly submitted by Hiroshi Miyata and posted to the IETF
repository.

Filename:	 draft-miyata-v6ops-snatpt
Revision:	 00
Title:		 sNAT-PT: Simplified Network Address Translation -
Protocol Translation
Creation_date:	 2008-02-01
WG ID:		 Independent Submission
Number_of_pages: 24

Abstract:
This document specifies an IPv4-to-IPv6 transition mechanism to provide
accessibility for IPv6 node to IPv4 node, and vice-versa.
The goal of this document is not providing the most fundamental
technology which could works well with additional technology.
We used to have an technology called NAT-PT[RFC2766]. NAT-PT was
designed to work with problematic DNS Application Level Gateway. So, it
was changed to historical state by [RFC4966].
This document attempts to simplify NAT-PT specification, removing
dependability on Application Layer Gateway as well as resolving problems
pointed in [RFC4966].

--------------------------------------

Actually, it is 24 pages, but if you know the original NAT-PT well, you
can skip some parts.

The major differences from original NAT-PT is as follows.

1) Remove ALG from Original NAT-PT
2) Add conceptual model to clarify the borderline between sAT-PT and  
ALGs.
3) Propose new  Dummy Prefix format.

This is aiming neither total nor perfect solution but aiming most basic
solution.
And it can be extended by additional technologies.
The packet translation technique is same as original NAT-PT.

Roughly speaking added and updated chapters are  2.5, 3, 4, 9, 10, 11.1,
11.2, 11.3, 13.

Thanks for your comment.
