MAIL TRANSITION PLAN

PREFACE

This is a draft memo and comments are requested.

INTRODUCTION

The principal aim of the mail service transition plan is to provide

orderly support for computer mail service during the period of

transition from the old ARPANET protocols to the new Internet

protocols.

This plan covers only the transition from the current text computer

mail in the ARPANET environment to text computer mail in an Internet

environment. This plan does not address a second transition from

text only mail to multimedia mail [10,11].

The goal is to provide equivalent or better service in the new

Internet environment as was available in the ARPANET environment.

During the interim period, when both protocol environments are in

use, the goal is to minimize the impact on users and existing

software, yet to permit the maximum mail exchange connectivity.

It is assumed that the user is familiar with both the ARPANET and

Internet protocol environments [1-8]. The Internet protocols are

designed to be used in a diverse collection of networks including the

ARPANET, Packet Radio nets, Satellite nets, and local nets (e.g.,

Ethernets, Ring nets); while the ARPANET protocol are, of course,

limited to the ARPANET.

The Internet protocol environment specifies TCP as the host-to-host

transport protocol. The ARPANET protocol environment specifies NCP

as the host-to-host transport protocol. Both TCP and NCP provide

connection type process-to-process communication. The problem in the

transition is to bridge these two different interprocess

communication systems.

The objective of this plan is to specify the means by which the

ARPANET computer mail services may be extended into the Internet

system without disruptive changes for the users during the

transition.

MODEL OF MAIL SERVICE

The model of the computer mail system taken here separates the mail

composition and reading functions from the mail transport functions.

In the following, the discussion will be hoplessly TOPS20-oriented.

We appologize to users of other systems, but we feel it is better to

discuss examples we know than to attempt to be abstract.

In the ARPANET mail service,...
