Frame Relay over ATM
ATM currently is the dominating backbone technology of modern public corporate network services
The main role of ATM so far has been in the interconnection of LANs
Frame Relay offers an efficient and economic way of connecting the existing communications equipment to ATM backbones
ATM Adaptation Layer 5 (AAL5) can easily implement Frame Relay as one of the many ATM based services
Frame Relay can efficiently use the ATM capacity left over by real-time ATM traffic
Frame Relay and ATM are not competing but rather complementing technologies that mix well
