Glossary
This chapter defines terms used in this guide and in the industry.
54G
TM
The internal wireless adapter from Broadcom.
ALG (Application-Level Gateway)
A type of security device that acts on behalf of the application servers on a network,
hiding the servers themselves from traffic that might be malicious.
AP (Access Point)
A device that allows wireless devices to connect to a wired network using WiFi, or related
standards.
Broadcast
A packet sent to all devices on a network.
BSS (Basic Service Sets)
A basic service set is the fundamental building block of an 802.11 wireless local area
network. The overlapping BSS problem refers to a situation where two or more systems,
unrelated to each other are in close enough proximity to hear each other physically.
Overlapping BSS may degrade the network performance severely.
BSSID (Basic Service Set Identifier)
The BSSID uniquely identifies a specific access point and is in the same format as a MAC
address.
Channel Bonding
A computer networking configuration where two or more network interfaces are combined
on a host computer for redundancy or increased throughput. Data is transmitted over
these channels as if they are one channel.
CMTS (Cable Modem Termination System)
Typically located in the cable company’s headend, the CMTS is equipment that provides
high-speed data services to subscribers, such as cable Internet and Voice over IP (VoIP).
CPE (Customer Premises Equipment)
Equipment such as telephones, routers, and modems located at a user’s location to
enable access to communication services.
Default Gateway
The routing device used to forward all traffic that is not addressed to a computer on the
local subnet.

DHCP (Dynamic Host Configuration Protocol)
A protocol that centrally automates the assignment of IP addresses in a network. Using
the Internet’s set of protocols (TCP/IP), each machine that can connect to the Internet
needs a unique IP address. For example, when the service provider sets up computer
users with a connection to the Internet, an IP address is assigned to each machine.
DHCP lets the service provider distribute IP addresses and automatically sends a new IP
address when a computer is plugged in to the high-speed Internet network. DHCP uses
the concept of a “lease” or amount of time an IP address is valid for a computer. Lease
times can vary.
DMZ (Demilitarized Zone)
Allows one IP address (or computer) to be placed in between the firewall and the Internet
(usually for gaming and video conferencing). This allows risky, open access to the
Internet.
DOCSIS (Data Over Cable Service Interface Specification)
An International telecommunications standard that permits the addition of high-speed data
transfer over an existing cable TV system.
Domain
A subnetwork comprised of a group of clients and servers under the control of one
security database.
Domain Name
A descriptive name for an address or group of addresses on the Internet. Domain names
are in the form of a registered entity name plus one of a number of predefined top-level
suffixes, such as .com, .edu, .org.
DoS (Denial of Service) Attack
An attempt to make a machine or network resources unavailable to its intended users.
DNS (Domain Name System)
An Internet service that locates and translates domain names into IP addresses. Because
domain names are alphabetic, they are easier to remember. However, the Internet is
based on IP addresses. Every time you use a domain name, a DNS service translates the
name into the corresponding IP address. The DNS system is actually its own network. If
one DNS server does not know how to translate a particular domain name, it asks another
one, and so on, until the correct IP address is returned.
Downstream
A term to describe the direction of data from the network service provider to the customer.
DTIM (Delivery Traffic Indication Message)
Informs clients about the presence of buffered broadcast data on the access point.
Ethernet
A standard network protocol that specifies how data is placed on and retrieved from a
common transmission medium. It forms the underlying transport vehicle used by several
upper-level protocols, including TCP/IP, HTTP, and FTP.

Firewall
A highly effective method to block unsolicited traffic from outside the connected
computers in your gateway and local network.
FTP (File Transfer Protocol)
A network protocol used to transfer files from one host to another over a TCP-based
network.
Gateway
A local device, usually a router, that connects hosts on a local network to other networks
– sometimes with different incompatible communication protocols. The DDW366 is an
example of a gateway.
Headend
A main facility to process and distribute Internet communication signals. Headend may
also refer to cable television signals and power line communication facilities.
ICQ
A free instant-messaging utility introduced by Mirabilis in 1996.
IKE (Internet Key Exchange)
A protocol used to ensure security for VPN negotiation and remote host or network
access.
IP (Internet Protocol)
The method or protocol by which data is sent from one computer to another on the
Internet. It is a standard set of rules, procedures, or conventions relating to the format and
timing of data transmission between two computers that they must accept and use to
understand each other. Used in conjunction with the Transfer Control Protocol (TCP) to
form TCP/IP.
IP Address
In the most widely installed level of the IP today, an IP address is a 32-bit binary digit
number that identifies each sender or receiver of information that is sent in packet form
across the Internet. When you request a Web page or send an e-mail, the IP part of
TCP/IP includes your IP address. IP sends your IP address to the IP address obtained by
looking up the domain name in the URL you requested or in the e-mail address to which
you are sending a note. A dynamic IP address is an IP address that is automatically
assigned to a client station in a TCP/IP network, typically by a DHCP server.
IPsec (Internet Protocol Security)
A protocol suite for securing Internet Protocol (IP) communications by authenticating and
encrypting each IP packet of a communication session.
IRC (Internet Relay Chat)
A system that facilitates the transfer of messages in the form of text.
ISP (Internet Service Provider)
A company that provides individuals and companies access to the Internet and other
related services.

IUC (Interval Usage Code)
Interval usage codes define different profiles for upstream burst profiles to use for the
data. IUCs are sent to the cable modem from the CMTS to tell the device important
characteristics to use for the burst, such as modulation type, preamble length, and so on.
Kerberos
A network authentication protocol which works on the basis of “tickets” to allow nodes
communicating over a non-secure network to prove their identity to one another in a
secure manner.
LAN (Local Area Network)
A group of computers and associated devices such as printers and servers that share a
common communication line and other resources within a small geographic area.
MAC (Media Access Control Address)
A unique number assigned by the manufacturer to any Ethernet networking device, such
as a network adapter, that allows the network to identify it at the hardware level. Usually
written in the form 01:23:45:67:89:ab.
Mbps (Megabits per Second)
A unit of measurement for data transmission that represents one million bits per second.
MTU (Maximum Transmission Unit)
The size in bytes of the largest packet that can be sent or received.
NAT (Network Address Translation)
A technique by which several hosts or computers share a single IP address for access to
the Internet. NAT enables a LAN to use one set of IP addresses for internal traffic and a
second set of addresses for external traffic, and provides a type of firewall by hiding
internal IP addresses.
NetBios (Network Basic Input/Output System)
A program that allows applications on different computers to communicate within a local
area network.
Net2Phone
A software/services company whose principal line of business is SIP-based and
PacketCable-based voice over IP.
Packet
A block of information sent over a network. A packet typically contains a source and
destination network address, some protocol and length information, a block of data, and a
checksum.
PPTP (Point-to-Point Tunneling Protocol)
A method for ensuring secure communication between virtual private networks.
