NCP/TCP TRANSITION PLAN

Introduction

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

ARPA sponsored research on computer networks led to the development

of the ARPANET. The installation of the ARPANET began in September

1969, and regular operational use was underway by 1971. The ARPANET

has been an operational service for at least 10 years. Even while it

has provided a reliable service in support of a variety of computer

research activities, it has itself been a subject of continuing

research, and has evolved significantly during that time.

In the past several years ARPA has sponsored additional research on

computer networks, principally networks based on different underlying

communication techniques, in particular, digital packet broadcast

radio and satellite networks. Also, in the ARPA community there has

been significant work on local networks.

It was clear from the start of this research on other networks that

the base host-to-host protocol used in the ARPANET was inadequate for

use in these networks. In 1973 work was initiated on a host-to-host

protocol for use across all these networks. The result of this long

effort is the Internet Protocol (IP) and the Transmission Control

Protocol (TCP).

These protocols allow all hosts in the interconnected set of these

networks to share a common interprocess communication environment.

The collection of interconnected networks is called the ARPA Internet

(sometimes called the "Catenet").

The Department of Defense has recently adopted the internet concept

and the IP and TCP protocols in particular as DoD wide standards for

all DoD packet networks, and will be transitioning to this

architecture over the next several years. All new DoD packet

networks will be using these protocols exclusively.

The time has come to put these protocols into use in the operational

ARPANET, and extend the logical connectivity of the ARPANET hosts to

include hosts in other networks participating in the ARPA Internet.

As with all new systems, there will be some aspects which are not as

robust and efficient as we would like (just as with the initial

ARPANET). But with your help, these problems can be solved and we

can move into an environment with significantly broader communication

services.

Discussion

----------

The implementation of IP/TCP on several hosts has already been

completed, and the use of some services is underway. It is urgent

that the implementation of of IP/TCP be begun on all other ARPANET

hosts as soon as possible and no later than 1 January 1982 in any

case. Any new host connected to t...
