Appendixes 
						

							80 Appendix A - TCP/IP Description
Multi-Tech Systems, Inc. MultiVOIP User Guide
Appendix A - TCP/IP Description
TCP/IP (Transmission Control Protocol/Internet Protocol) is a protocol suite and related
applications developed for the U.S. Department of Defense in the 1970s and 1980s specifically to
permit different types of computers to communicate and exchange information with one another.
TCP/IP is currently mandated as an official U.S. Department of Defense protocol and is also
widely used in the UNIX community.
Before you install TCP/IP on your network, you need to establish your Internet addressing
strategy. First, choose a domain name for your company. A domain name is the unique Internet
name, usually the name of your business, that identifies your company. For example, Multi-Tech’s
domain name is multitech.com ( .com indicates this is a commercial organization; .edu denotes
educational organizations, .gov denotes government organizations). Next, determine how many
IP addresses you’ll need. This depends on how many individual network segments you have, and
how many systems on each segment need to be connected to the Internet. You’ll need an IP
address for each network interface on each computer and hardware device.
IP addresses are 32 bits long and come in two types: network and host. Network addresses
come in five classes: A, B, C, D, and E. Each class of network address is allocated a certain
number of host addresses. For example, a class B network can have a maximum of 65,534
hosts, while a class C network can have only 254. The class A and B addresses have been
exhausted, and the class D and E addresses are reserved for special use. Consequently,
companies now seeking an Internet connection are limited to class C addresses.
Early IP implementations ran on hosts commonly interconnected by Ethernet local area networks
(LAN). Every transmission on the LAN contains the local network, or medium access control
(MAC), address of the source and destination nodes. The MAC address is 48-bits in length and is
non-hierarchical; MAC addresses are never the same as IP addresses.
When a host needs to send a datagram to another host on the same network, the sending
application must know both the IP and MAC addresses of the intended receiver. Unfortunately,
the IP process may not know the MAC address of the receiver. The Address Resolution Protocol
(ARP), described in RFC 826 (located at ftp://ds.internic.net/rfc/rfc826.txt) provides a mechanism
for a host to determine a receiver’s MAC address from the IP address. In the process, the host
sends an ARP packet in a frame containing the MAC broadcast address; and then the ARP
request advertises the destination IP address and asks for the associated MAC address. The
station on the LAN that recognizes its own IP address will send an ARP response with its own
MAC address. An ARP message is carried directly in an IP datagram.
Other address resolution procedures have also been defined, including those which allow a
diskless processor to determine its IP address from its MAC address (Reverse ARP, or RARP),
provides a mapping between an IP address and a frame relay virtual circuit identifier (Inverse
ARP, or InARP), and provides a mapping between an IP address and ATM virtual path/channel
identifiers (ATMARP).
The TCP/IP protocol suite comprises two protocols that correspond roughly to the OSI Transport
and Session Layers; these protocols are called the Transmission Control Protocol and the User
Datagram Protocol (UDP). Individual applications are referred to by a port identifier in TCP/UDP
messages. The port identifier and IP address together form a “socket”. Well-known port numbers
on the server side of a connection include 20 (FTP data transfer), 21 (FTP control), 23 (Telnet),
25 (SMTP), 43 (whois), 70 (Gopher), 79 (finger), and 80 (HTTP).
TCP, described in RFC 793 ( ftp://ds.internic.net/rfc/rfc793.txt) provides a virtual circuit
(connection-oriented) communication service across the network. TCP includes rules for
formatting messages, establishing and terminating virtual circuits, sequencing, flow control, and
error correction. Most of the applications in the TCP/IP suite operate over the “reliable” transport
service provided by TCP.
