Discrete-Time Queuing Analysis of Dual-Plane ATM Switch with Synchronous Connection Control

Abstract

In this paper, we propose an ATM switch with the rate more than gigabits per second to cope with future broadband service environments. The basic idea is to separate the connection control flow from the data information flow inside the switch. The proposed switch has a dual-plane switch matrix with the synchronous control algorithm. The queuing behaviors of the proposed switch are shown by the discrete-time queuing analysis. Numerical analyses are taken both in the non-blocking crossbar switch and the banyan switch with internal blocking. Results show that a proposed dual-plane 16×16 switch would have the acceptable performance with maximum throughput of about 95 percent.
