RFC 872 September 1982

M82-48

TCP-ON-A-LAN

M.A. PADLIPSKY

THE MITRE CORPORATION

Bedford, Massachusetts

Abstract

The sometimes-held position that the DoD Standard

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

are inappropriate for use "on" a Local Area Network (LAN) is

shown to be fallacious. The paper is a companion piece to

M82-47, M82-49, M82-50, and M82-51.

"TCP-ON-A-LAN"

M. A. Padlipsky

Thesis

It is the thesis of this paper that fearing "TCP-on-a-LAN"

is a Woozle which needs slaying. To slay the "TCP-on-a-LAN"

Woozle, we need to know three things: What's a Woozle? What's a

LAN? What's a TCP?

Woozles

The first is rather straightforward [1]:

One fine winter's day when Piglet was brushing away the

snow in front of his house, he happened to look up, and

there was Winnie-the-Pooh. Pooh was walking round and round

in a circle, thinking of something else, and when Piglet

called to him, he just went on walking.

"Hallo!" said Piglet, "what are you doing?"

"Hunting," said Pooh.

"Hunting what?"

"Tracking something," said Winnie-the-Pooh very

mysteriously.

"Tracking what?" said Piglet, coming closer.

"That's just what I ask myself. I ask myself, What?"

"What do you think you'll answer?"

"I shall have to wait until I catch up with it," said

Winnie-the-Pooh. "Now look there." He pointed to the

ground in front of him. "What do you see there?

"Tracks," said Piglet, "Paw-marks." he gave a little

squeak of excitement. "Oh, Pooh! Do you think it's a--a--a

Woozle?"

Well, they convince each other that it is a Woozle, keep

"tracking," convince each other that it's a herd of Hostile

Animals, and get duly terrified before Christopher Robin comes

along and points out that they were following their own tracks

all the long.

In other words, it is our contention that expressed fears

about the consequences of using a particular protocol named "TCP"

in a particular environment called a Local Area Net stem from

misunderstandings of the protocol and the environment, not from

the technical facts of the situation.

LAN's

The second thing we need to know is somewhat less

straightforward: A LAN is, properly speaking [2], a
