Abstract

This paper proposes a high-speed crosspoint-buffer-type ATM switch, named Scalable -Distributed-Arbitration (SDA) switch. The SDA switch employs a new arbitration that is enable the switch to have scalability. The SDA switch has a crosspoint buffer and transit buffer at every crosspoint. The arbitration is executed between the crosspoint buffer and the transit buffer. The arbitration selects a cell based on delay time using a synchronous counter. The selected cell is transferred from a crosspoint buffer by way of several transit buffers, then to the output port. Since the arbitration is executed distributedly at each crosspoint and the arbitration time does not depend on the switch size, the SDA switch is able to be expandable and have large throughput. Numerical results show that the SDA switch keeps fairness on delay time. In addition. the maximum delay time and the required crosspoint buffer size in the SDA switch was reduced, compared with that in the conventional switch based on the ring arbitration. Thus, the proposed SDA switch based on the new arbitration scheme is a simple and expandable architecture, and it will be suitable for the future high-speed multimedia ATM networks.
