The CTDP Networking Guide Version 0.6.3 February
Revised to Version 0.6.4 November, 4, 2002
This guide is primarily about TCP/IP network protocols and ethernet network architectures, but also
briefly describes other protocol suites, network architectures, and other significant areas of networking.
This guide is written for all audiences, even those with little or no networking experience. It explains in
simple terms the way networks are put together, and how data packages are sent between networks and
subnets along with how data is routed to the internet. This document is broken into five main areas which
Basics - Explains the protocols and how they work together
Media - Describes the cabling and various media used to send data between multiple points of a
Architecture - Describes some popular network architectures. A network architecture refers to the
physical layout (topology) of a network along with the physical transmission media (Type of wire,
wireless, etc) and the data access method (OSI Layer 2). Includes ethernet, Token Ring, ARCnet,
AppleTalk, and FDDI. This main area of the document can and should be skipped by those
learning networking and read later.
Other Transport Protocols - Describes IPX/SPX, NetBEUI, and more.
Functions - Explains some of the functionality of networking such as routing, firewalls and DNS.
Further Details - Gives information about some protocols not covered in the "Basics" section. In
the future, it will include more information about packet fragmentation and re-assembly along
with more details about UDP and especially TCP and TCP connections.
More Complex functions - Documents multicasting, dynamic routing, and network management
Applications - Documents how some of the applications work such as ping and traceroute. In the
future, it will cover telnet, Rlogin, and FTP.
Other Concerns - Includes installing drivers, network operating systems, applications, wide area
networks, backing up the network and troubleshooting the network.
References - Includes a reference list of terms, RFCs and recommended reading.
The reader may read this document in any order, but for beginners, it would be best to read through from
the beginning with the exception of sections 2 (media), 3 (architecture), and 4 (other). At some point,
however, the reader should be able to break from the basics and read about routing and IP masquerading.
