                       Joining the Global IP Internet

Overview

  With the availability of easily configured IP routers that can use the
Public Switched Telephone System, the network of IP internets is growing
phenomenally. There are many advantages to IP networks. One of the biggest
advantages is the existance of the global IP Internet.

  This network is composed of Government networks and Research and Educational
networks, and recently, full commercial networks as well. All these networks
are joined by gateways, allowing the full range of IP services (such as FTP,
Telnet, and applications such as X windows) to be exchanged.

  The availability of sophisticated software such as compilers, X window
system, and numerous other utilities makes access to the  IP Internet
a distinct advantage in today's internetworking environment.
This note will describe the various items necessary for obtaining
a fully supported connection to the  IP Internet.

Basic Walkthrough

  The following items will be necessary for supporting the internet connection.
It is assumed that the reader has obtained one or more of the references
listed in the appendix, and will understand the need for the various items
as this note mentions them. In addition, the Network Information Center
(NIC) will be consulted for Network number assignment and domain registration.
The contact information for the NIC is in the appendix.

1. Obtaining an IP network number

  An officially registered Network number must be obtained from the appropriate
party. This number uniquely identifies the IP network. The NIC will assign the
network number based upon the needs of your organization. The various classes
of network numbers are described in the TCP/IP reference listed in the
appendix.

  Once the network address is obtained, you are then able to assign individual
host numbers to entities on your IP network. Each network entity must have
a unique host number. One of the most important addresses that you must
assign is the address of your Domain Name System (DNS) server. You must
have a network number to assign host addresses for your DNS server before
you can complete the Domain Application form from the NIC (see next section).

2. Registering a Domain

  A Domain Name is also registered at the NIC. The domain name uniquely
identifies your organization in the Internet community. It is used
in electronic mail addresses, and many other IP services. See the appendix
for a reference volume for the Domain Name System (DNS). The NIC will
refuse to register a domain unless there are two servers for the domain.
The two servers are a primary and a secondary. Two servers are required
for reliability, and it is strongly recommended that the servers be
physically separated. Most often, an organization will run its own
primary server, and the secondary is off-site. The off-site server
can be arbitrary, and often is simply a "network neighbor." The
commercial IP network providers can also act as DNS servers for
smaller sites.

3. Physical Interconnection Issues

  The physical connection must be supported with an IP router. The router
can use a telephone company (telco) leased line for high speed, or the
regular Public Switched Telephone System for low cost. The router is what
directs network traffic outside your local organization, and into and out
of the  internet. The flexibility of the IP protocols is especially
apparent here, with numerous options available for transport and
interconnection of various IP network segments. Options include optical
fiber, satellite relay, microwave transmission, or the common telco lines.
Consult the router vendors listed in the appendix for further information.

4. Network Service Providers

There are several entities that can be contacted
for obtaining interconnection to the internet. Military users generally
are attached to the Defense Data Network (DDN). Research and Educational
institutions often connect via the National Science Foundation network
(NSFnet). Recently, full commercial IP networks have been placed into
operation. The commercial networks generally have fewer restrictions
on the traffic they will carry as compared to the Military and Research
networks. The appendix lists contacts for some of these transport agencies.

5. Tying It All Together

Once you have a network address, and have your domain registered, you can
begin building the network connection. Coordinate with your network sevice
provider for the appropriate access method, for instance a dialup IP link
via SLIP or PPP. The telephone company may need to install circuits if a
high speed leased line is required. Once the leased line (or other access
method) is in place, you can test the LAN access. Consult your vendors
documents for appropriate configuration commands. Once your IP routers
are configured for your network topology, the packets should flow.
Congratulations, you're now a member in good standing of the IP Internet
community.

The Simple Book
Marshall Rose
Prentice Hall

The Internet Standard Simple Network Management Protocol (SNMP) is given
a thorough treatment by the author. Because of the nature of managing a
network with SNMP, the internet protocols are given a wring out in the text.

_________________________________
Computer Networks, Second Edition
Andrew Tannenbaum
Prentice Hall

A comprehensive overview of various networking implementations including
TCP/IP, DECnet, SNA, x.25, and various transport agents such as ethernet,
token ring, packet radio, and others.

DDN Protocol Handbook
SRI International

This four volume set contains sufficient information to code a functional
TCP/IP protocol implementation from. A number of Request For Comments
(RFC's) are listed in the handbook.

____________________
Request For Comments
(various authors)

The Request For Comment (RFC) is the mechanism used by the Internet Community
to define protocol standards. Several sites make the RFC's available for
copying from the network free of charge. Hard copy service is provided by
SRI International.
