DHCP, DHCP Client, DHCP Server

DHCP (the Dynamic Host Control Protocol) is the protocol that a DHCP client uses
to communicate with a DHCP server to ask for an IP address to be assigned. Other
network parameters that can be assigned using the DHCP protocol include network
mask, the primary DNS IP address, the secondary DNS IP address, the default
gateway IP address, WINS Server addresses, NetBIOS Node Type, etc.

Edge Router

A router that resides at the edge of a network. It is like a gateway that is used to
communicate with the outside network.

Encryption

A method for scrambling data which inhibits unauthorized snooping. To ensure
privacy of data sent over the network, the data is often encrypted before it is sent out,
and decrypted when it is received. This is used to protect private data from being
pirated, especially when data is sent over the WAN.

Dial-on-Demand, Bandwidth-on-Demand

If the user uses a switched (dial-up) service to access the Internet, the associated
telecomm cost is often directly proportional to the amount of time the user uses the
network service to connect to the Internet. Therefore often it is designed so that the
connection will be triggered only when there is a need - such as when a user tries to
use a web browser to access the Internet.

For ISDN, when there is a demand, the device will first bring up one B channel to
provide 64Kbps (or 56Kbps) data bandwidth. If traffic is heavy, such as when more
users want to access the Internet, the user can configure the device to bring up the
second B channel to provide higher data bandwidth. Such a capability is called
Bandwidth-on-Demand.

EWAN

The EWAN(Ethernet Wide Area Network) Port is where you will connect your cable
or DSL modem

Flash Memory

This is a special read-write memory in a computer system that allows the computer
program (firmware) or the user configuration data to be stored. Its content will
continue to exist even when the power is turned off.

ICMP

The Internet Control Message Protocol (ICMP) is part of the TCP/IP protocol suite,
which is often used for error reporting and control purposes, including the use of the
diagnostic PING command.

Idle Timeout

The Idle Timeout is an amount of time during which no productive data transfer
