AAL5: ATM Adaptation Layer Type 5

ATM Adaptation Layer Type 5 (AAL5) is designed for variable bit rate, delay-tolerant connection-oriented data traffic requiring minimal sequencing or error detection support. AAL5 supports connection-oriented, VBR services. AAL5 is used predominantly for the transfer of classic IP over ATM and LANE traffic. AAL5 uses SEAL and is the least complex of the current AAL recommendations. AAL5 has no per-cell length or per-cell CRC fields, and offers low bandwidth overhead and simpler processing requirements in exchange for reduced bandwidth capacity and error-recovery capability.
