AAL
ATM Adaptation Layer — A set of protocols that
translate user higher-layer protocols into ATM cell
format. The AAL is divided into the Convergence
Sublayer (CS) and the Segmentation and Reassembly
(SAR) sublayer.
ANSI
American National Standards Institute. A United
States technology standards organization.
ARP
Address Resolution Protocol — See LE_ARP.
ASIC
Application Specific Integrated Circuit.
ATM
Asynchronous Transfer Mode — A connection
oriented transmission protocol based on fixed length
cells (packets) of 53 bytes (including a 5-byte cell
header) in length.
The ATM concept was defined by ANSI and ITU
(formerly CCITT) for carrying a complete range of user
traffic, including voice, data and video signals, on any
User-To-Network Interface (UNI).
ATM Forum
A consortium of organizations representing vendors,
manufacturers, carriers, service providers, universities,
research groups, consultants and users.
The ATM Forum recommends and defines
specifications for ATM standards, promotes industry
cooperation in the implementation of ATM
technologies, and encourages the use of ATM
products and services.
ATM Switch
An ATM device responsible for switching the cells.
B-ISDN
Broadband Integrated Services Digital Network — A
protocol platform to support the integrated,
high-speed transmission of data, audio and video in a
seamless fashion. ATM emerged as a suitable
transport standard.
BUS
Broadcast and Unknown Server — A server that
forwards multicast, broadcast and unknown
destination address traffic to the LECs attached to the
Emulated LAN.
