ATM adaptation layer 5
One of
four AALs recommended by the ITU-T. AAL5 supports connection-oriented, VBR
services, and is used predominantly for the transfer of classical IP over ATM
and LANE traffic. AAL5 uses SEAL and is the least complex of the current AAL
recommendations. It offers low bandwidth overhead and simpler processing
requirements in exchange for reduced bandwidth capacity and error-recovery
capability. See also AAL and SEAL.
