In this paper, we propose an ATM switch with the rate more than gigabi
ts per second to cope with future broadband service environments. The
basic idea is to separate the connection control flow from the data in
formation flow inside the switch. The proposed switch has a dual-plane
switch matrix with the synchronous control algorithm. The queuing beh
aviors of the proposed switch are shown by the discrete-time queuing a
nalysis. Numerical analyses are taken both in the nonblocking crossbar
switch and the banyan switch with internal blacking. Results show tha
t a proposed dual-plane 16x16 switch would have the acceptable perform
ance with maximum throughput oi about 95 percent.
