Atm Adaptation LayerIn ATM networks, the ATM Adaptation Layer is the point where data is translated into a form that can be segmented and reassembled at the other end. There are four recommended AALs: - AAL1: used for services like uncompressed video that require a steady bit rate
- AAL2: used for voice traffic tat can handle a variable bit rate
- AAL3/4: used for SMDS packets
- AAL5: used for IP traffic
