WLAN ADSL2+ Router

7.0 Technology Glossary

10Base-T

An adaptation of the 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.

Address mask

A bit mask used to select bits from an Internet address for subnet addressing. The mask is 32

bits long and selects the network portion of the Internet address and one or more bits of the

local portion. Sometimes called subnet mask.

ADSL

Asymmetric Digital Subscriber Line, as it’s name showing, is an asymmetrical data

transmission technology with high traffic rate downstream and low traffic rate upstream. ADSL

technology satisfies the bandwidth requirement of applications, which demand “asymmetric”

traffic, such as web surfing, file download and Video-on-demand (VOD).

ATM

Asynchronous Transfer Mode is a layer 2 protocol supporting high-speed asynchronous data

with advanced traffic management and quality of service features.

bps

Bits per second. A standard measurement of digital transmission speeds.

Bridge

A device that connects two or more physical networks and forwards packets between them.

Bridges can usually be made to filter packets, that is, to forward only certain traffic. Related

devices are: repeaters which simply forward electrical signals from one cable to the other, and

full-fledged routers which make routing decisions based on several criteria.

CPE

Customer Premises Equipment, such as ADSL router, USB modem.

DHCP

Dynamic Host Configuration Protocol. Used for assigning dynamic IP address to devices on a

network. Used by ISPs for dialup users.

DNS

Domain Name Server, translates domain names into IP addresses to help user recognize and

remember. However, the Internet actually runs on numbered IP addresses, DNS servers

needs to translate domain names back to their respective IP addresses.

DSL

Digital Line Subscriber (DSL) technology provides high-speed access over twisted copper pair

for connection to the Internet, LAN interfaces, and to broadband services such as

video-on-demand, distance learning, and video conferencing.

FTP

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

hosts.

IPoA (RFC 1577)

Classical IP and ARP over ATM. Considers ATM configured as a Logic IP Sub-network(LIS) to

replace Ethernet local LAN segments.

ISP

Internet service provider. A company that allows home and corporate users to connect to the

Internet.

LAN

Local area network. A limited distance (typically under a few kilometers or a couple of miles)

high-speed network (typically 4 to 100 Mbps) that supports many computers.

MAC

Media Access Control Layer. A sub-layer of the Data Link Layer (Layer 2) of the ISO OSI

Model responsible for media control.

MTU

Maximum Transmission Unit

NAT

Network Address Translator as defined by RFC 1631. Enables a LAN 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.

PPP

Point-to-Point-Protocol. The successor to SLIP, PPP provides router-to-router and

host-to-network connections over both synchronous and asynchronous circuits.

PPPoA (RFC 2364)

The Point-to-Point Protocol(PPP) provides a standard method for transporting multi-protocol

datagrams 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 Concentrator.

PVC

Permanent Virtual Circuit. Connection-oriented permanent leased line circuit between

end-stations on a network over a separate ATM circuit.

RFC

Request for Comments. The document series, begun in 1969, which describes the Internet suite

of protocols and related experiments. Not all RFCs describe Internet standards, but all Internet

standards are written up as RFCs

RFC 1483

Multi-protocol encapsulation over AAL-5. Two encapsulation methods for carrying network

interconnect traffic over ATM AAL-5. The first method allows multiplexing of multiple protocols

over a single ATM virtual circuit.

The protocol of a carried PDU is identified by prefixing the

PDU by an IEEE 802.2 Logical Link Control (LLC) header.

This method is in the following

called "LLC Encapsulation". The second method does higher-layer protocol multiplexing

implicitly by ATM Virtual Circuits (VCs).

It is in the following called "VC Based Multiplexing".

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.

Spanning Tree

Spanning-Tree Bridge Protocol (STP). Part of an IEEE standard. A mechanism for detecting

and preventing loops from occurring in a multi-bridged environment. When bridges connect

three or more LAN segments, a loop can occur. Because a bridge forwards all packets that are

not recognized as being local, some packets can circulate for long periods of time, eventually

degrading system performance. This algorithm ensures only one path connects any pair of

stations, selecting one bridge as the 'root' bridge, with the highest priority one as identifier,

from which all paths should radiate.

TELNET

The virtual terminal protocol in the Internet suite of protocols. Allows users of one host to log

into a remote host and act as normal terminal users of that host.

VCI

Virtual Circuit Identifier. Part of the ATM cell header, a VCI is a tag indicating the channel over

which a cell will travel. The VCI of a cell can be changed as it moves between switches via

Signaling.

VPI

Virtual Path Identifier. Part of the ATM cell header, a VPI is a pipe for a number of Virtual

Circuits.

WAN

Wide area network. A data communications network that spans any distance and is usually

provided by a public carrier (such as a telephone company or service provider)
