Abstract

This tutorial contains only one view of the salient points of TCP/IP, and therefore it is the "bare bones" of TCP/IP technology. It omits the history of development and funding, the business case for its use, and its future as compared to ISO OSI. Indeed, a great deal of technical information is also omitted. What remains is a minimum of information that must be understood by the professional working in a TCP/IP environment. These professionals include the systems administrator, the systems programmer, and the network manager.

A TCP/IP Tutorial

Status of this Memo

This RFC is a tutorial on the TCP/IP protocol suite, focusing

particularly on the steps in forwarding an IP datagram from source

host to destination host through a router. It does not specify an

Internet standard. Distribution of this memo is unlimited.

1. Introduction

This tutorial contains only one view of the salient points of TCP/IP,

and therefore it is the "bare bones" of TCP/IP technology. It omits

the history of development and funding, the business case for its

use, and its future as compared to ISO OSI. Indeed, a great deal of

technical information is also omitted. What remains is a minimum of

information that must be understood by the professional working in a

TCP/IP environment. These professionals include the systems

administrator, the systems programmer, and the network manager.

This tutorial uses examples from the UNIX TCP/IP environment, however

the main points apply across all implementations of TCP/IP.

Note that the purpose of this memo is explanation, not definition.

If any question arises about the correct specification of a protocol,

please refer to the actual standards defining RFC.

The next section is an overview of TCP/IP, followed by detailed

descriptions of individual components.

2. TCP/IP Overview

The generic term "TCP/IP" usually means anything and everything
