7. Glossary 
10Base-T 
It is an Ethernet standard for Local Area Network (LAN). 10Base-T uses a twisted 
pair cable with maximum length of 100 meters. 
 
AAL 
ATM Adaptation Layer that defines the rules governing segmentation and 
reassembly of data into cells. Different AAL types are suited to different traffic 
classes. 
 
ADSL 
Asymmetric Digital Subscriber Line, as its name showing, is an asymmetrical 
data transmission technology with high traffic rate downstream and low traffic 
rate upstream....

 64 CPE 
Customer Premises Equipment, such as ADSL router, USB modem. 
 
Default Gateway (Router) 
Every non-router IP device needs to configure a default gateway’s IP address. 
When the device sends out an IP packet, if the destination is not on the same 
network, the device has to send the packet to its default gateway, which will then 
send it out towards the destination. 
 
DHCP 
Dynamic Host Configuration Protocol, this protocol automatically gives every 
computer on your home network an IP address....

 65 FTP 
File Transfer Protocol. The Internet protocol (and program) used to transfer files

 66 NAT 
Network Address Translator is defined by RFC 1631. Enable a LAN network to 
use one set of IP address for internal traffic. A NAT box located where the LAN 
meets the Internet provides the necessary IP address translation. This helps 
provide a sort of firewall and allow for a wider address range to be used internally 
without danger of conflict. Using the router’s NAT capability, you can access the 
Internet from any computer on your home network without having to purchase 
more IP addresses...

 67 PPPoA (RFC 2364) 
The Point-to-Point Protocol (PPP) provides a standard method for transporting 
multi-protocol data grams over point-to-point links. This document describes the 
use of ATM Adaptation Layer 5 (AAL5) for framing PPP encapsulated packets. 
 
PPPoE (RFC 2516) 
This document describes how to build PPP sessions and encapsulate PPP 
packets over Ethernet. PPP over Ethernet (PPPoE) provides the ability to 
connect a network of hosts over a simple bridging access device to a remote 
Access...

 68 Router 
A system responsible for making decisions about which of several paths network 
(or Internet) traffic will follow. To do this, it uses a routing protocol to gain 
information about the network and algorithms to choose the best route based on 
several criteria known as routing metrics. 
 
Subnet Mask 
A subnet mask, which may be a part of the TCP/IP information provided by your 
ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an IP address. 
It is used to create IP address...
