ATM adaptation layer
ASYNCHRONOUS TRANSFER MODE NETWORKING TECHNOLOGY
AAL3; AAL4; AAL3/4; AAL (ATM Adaptation Layer); ATM Adaptation Layers; ATM Adaptation Layer; AAL0
The use of Asynchronous Transfer Mode (ATM) technology and services creates the need for an adaptation layer in order to support information transfer protocols, which are not based on ATM. This adaptation layer defines how to segment higher-layer packets into cells and the reassembly of these packets.
