DHCP relay

Dynamic Host Configuration Protocol relay. A DHCP relay is a computer that

 

forwards DHCP data between computers that request IP addresses and the DHCP

 

server that assigns the addresses. Each of the My ADSL Modem’s interfaces can

 

be configured as a DHCP relay. See DHCP.

DHCP server

Dynamic Host Configuration Protocol server. A DHCP server is a computer that is

 

responsible for assigning IP addresses to the computers on a LAN. See DHCP.

digital

Of data, having a form based on discrete values expressed as binary numbers (0’s

 

and 1’s). The data component in DSL is a digital signal. See also analog.

DNS

Domain Name System. The DNS maps domain names into IP addresses. DNS

 

information is distributed hierarchically throughout the Internet among computers

 

called DNS servers. When you start to access a web site, a DNS server looks up

 

the requested domain name to find its corresponding IP address. If the DNS server

 

cannot find the IP address, it communicates with higher-level DNS servers to

 

determine the IP address. See also domain name.

domain name

A domain name is a user-friendly name used in place of its associated IP address.

 

For example, www.globespan.net is the domain name associated with IP address

 

209.191.4.240. Domain names must be unique; their assignment is controlled

 

by the Internet Corporation for Assigned Names and Numbers (ICANN). Domain

 

names are a key element of URLs, which identify a specific file at a web site, e.g.,

 

http://www.netcomm.com.au. See also DNS.

download

To transfer data in the downstream direction, i.e., from the Internet to the user.

DSL

Digital Subscriber Line A technology that allows both digital data and analog voice

 

signals to travel over existing copper telephone lines.

Ethernet

Local area network traffic will be carried by standard Category 5 cable referred to

 

as Ethernet. The most commonly installed computer network technology, usually

 

using twisted pair wiring. Ethernet data rates are 10 Mbps and 100 Mbps. See also

 

BASE-T,100BASE-T, twisted pair.

Filtering

To screen out selected types of data, based on filtering rules. Filtering can be ap-

 

plied in one direction (upstream or downstream), or in both directions.

filtering rule

A rule that specifies what kinds of data a routing device will accept and/or reject.

 

Filtering rules are defined to operate on an interface (or multiple interfaces) and in

 

a particular direction (upstream, downstream, or both).

Firewall

Any method of protecting a computer or LAN connected to the Internet from intru-

 

sion or attack from the outside. Some firewall protection can be provided by packet

 

filtering and Network Address Translation services.

FTP

File Transfer Protocol - A program used to transfer files between computers con-

 

nected to the Internet. Common uses include uploading new or updated files to a

 

web server, and downloading files from a web server.

GGP

Gateway to Gateway Protocol. An Internet protocol that specifies how gateway rout-

 

ers communicate with each other.

Gbps

Abbreviation for Gigabits (GIG-uh-bits) per second, or one billion bits per second.

 

Internet data rates are often expressed in Gbps.

GRE

Generic Routing Encapsulation. TCP/IP protocol suite, transport layer encapsulation

 

protocol.
