AAL3/4: ATM Adaptation Layer Type 3/4

ATM Adaptation Layer Type 3/4 (AAL3/4) is designed for variable bit rate, delay-tolerant data traffic requiring some sequencing and/or error detection support. AAL 3/4 supports both connectionless and connection-oriented links, but is primarily used for the transmission of SMDS packets over ATM networks.
