An internal speed-up crossbar-type ATM switch architecture is proposed. This switch accommodates 10 Gbit/s cell streams from AHMs in order to guarantee the QoS of switched cells. A new high-speed arbitration algorithm using three buses on each output line, called the bi-directional arbiter, is used. It handles output contention about twice as fast as the conventional ring-arbiter and has the same fairness function. It increases the switch throughput to 160 Gbit/s efficiently. By combining the high-speed switch and AHMs, it will be able to make a sub-terabit/s ATM switching system for future Broadband ISDN networks.
