Domain Name

A descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a

registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For

example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.

DSL

Short for digital subscriber line, but is commonly used in reference to the asymmetric version of this

technology (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5

to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data

(known as the upstream rate).

ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world

gain access.

Dynamic Host Configuration Protocol

DHCP. An Ethernet protocol specifying how a centralized DHCP server can assign network configuration

information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and

gateway (router) addresses.

EAP

Extensible Authentication Protocol is a general protocol for authentication that supports multiple

authentication methods.

EAP, an extension to PPP, supports such authentication methods as token cards, Kerberos, one-time

passwords, certificates, public key authentication and smart cards. In wireless communications using EAP, a

user requests connection to a WLAN through an AP, which then requests the identity of the user and

transmits that identity to an authentication server such as RADIUS. The server asks the AP for proof of

identity, which the AP gets from the user and then sends back to the server to complete the authentication.

EAP is defined by RFC 2284.

Endstation

A computer, printer, or server that is connected to a network.

Ethernet

A LAN specification developed jointly by Xerox, Intel and Digital Equipment Corporation. Ethernet

networks transmit packets at a rate of 10 Mbps.

Fast Ethernet

An Ethernet system that is designed to operate at 100 Mbps.

Fault isolation

A technique for identifying and alerting administrators about connections (such as those associated with

switch ports) that are experiencing congestion or failure, or exceeding an administrator-defined threshold.

Forwarding

The process of sending a packet toward its destination using a networking device.
