A 160 Gbit/s large-capacity ATM switching system using a dynamic link speed controlled switch architecture

This paper describes the architecture and implementation of a 160 Gbit/s ATM switch based on CMOS LSI technology. To construct the switch, a new high-speed switch element using dynamic link speed control is proposed. Each element offers 16 2.4 Gbit/s ports and employs the parallel memory accessing technique with bit slice LSI fabrication. The switch element achieves double the throughput of conventional switch elements. Using the proposed switch elements, a 160 Gbit/s throughput large capacity ATM switching system can be realized. The prototype of ATM switching system using proposed switch architecture was developed
