11. Technology Glossary
An adaptation of the Ethernet standard for Local Area Network (LAN). 10Base-T uses a twisted pair
cable with maximum length of 100 meters.
ATM Adaptation Layer that defines the rules governing segmentation and reassembly of data into cells.
Different AAL types are suited to different traffic classes.
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.
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).
Asynchronous Transfer Mode is a layer 2 protocol supporting high-speed asynchronous data with
advanced traffic management and quality of service features.
Bits per second. A standard measurement of digital transmission speeds.
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.
Customer Premises Equipment, such as ADSL router, USB modem.
Dynamic Host Configuration Protocol. Used for assigning dynamic IP address to devices on a network.
Used by ISPs for dialup users.
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.
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.
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.
Internet service provider. A company that allows home and corporate users to connect to the Internet.
