AAL stands for ATM Adaptation Layer, a networking framework that bridges user data streams and the fixed 53-byte cell structure of Asynchronous Transfer Mode (ATM) networks. It segments variable-length packets, voice streams, or video feeds into small payloads and reassembles them at the destination. Different AAL types handle specific traffic profiles, ensuring that timing-sensitive voice and bursty computer data can share the same physical infrastructure.
