Logic design on FPGA of ATM SAR function in broadband access network

The logic design on FPGAs of the ATM SAR function in broadband access networks is studied. AAL which adapts services to the ATM cell is the adaptation layer between the ATM layer and the high layer. FR and Ethernet data services should adapt the ATM cell with AAL5. Segmentation, reassembly process and traffic control issues are also discussed.
