and adapted the original model to a broader arena than had initially been contemplated, were also consulted.) That might not sound so impressive as a pronunciamento from an international standards organization, but the reader should be somewhat consoled by the consideration that not only are the views expressed here purported to be those of the primary workers in the field, but also at least one Englishman helped out in the review process.

A PERSPECTIVE ON THE ARPANET REFERENCE MODEL

M.A. PADLIPSKY

THE MITRE CORPORATION

Bedford, Massachusetts

Abstract

The paper, by one of its developers, describes the

conceptual framework in which the ARPANET intercomputer

networking protocol suite, including the DoD standard

Transmission Control Protocol (TCP) and Internet Protocol (IP),

were designed. It also compares and contrasts several aspects of

the ARPANET Reference Model (ARM) with the more widely publicized

International Standards Organization's Reference Model for Open

System Interconnection (ISORM).

"A PERSPECTIVE ON THE ARPANET REFERENCE MODEL"

M. A. Padlipsky

Introduction

Despite the fact that "the ARPANET" stands as the

proof-of-concept of intercomputer networking and, as discussed in

more detail below, introduced such fundamental notions as

Layering and Virtualizing to the literature, the wide

availability of material which appeals to the International

Standards Organization's Reference Model for Open System

Interconnection (ISORM) has prompted many new- comers to the

field to overlook the fact that, even though it was largely

tacit, the designers of the ARPANET protocol suite have had a

reference model of their own all the long. That is, since well

before ISO even took an interest in "networking", workers in the

ARPA-sponsored research community have been going about their

business of doing research and development in intercomputer

networking with a particular frame of reference in mind. They

have, unfortunately, either been so busy with their work or were

perhaps somehow unsuited temperamentally to do learned papers on

abstract topics when there are interesting things to be said on

specific topics, that it is only in very recent times that there

has been much awareness in the research community of the impact

of the ISORM on the lay mind. When the author is asked to review

solemn memoranda comparing such things as the ARPANET treatment

of "internetting" with that of CCITT employing the ISORM "as the

frame of reference," however, the time has clearly come to

attempt to enunciate the ARPANET Reference Model (ARM)

publicly--for such comparisons are painfully close to comparing

an orange with an apple using redness and smoothness as the

dominant criteria, given the philosophical closeness of the CCITT

and ISO models and their mutual disparities from the ARPANET

model.
