A modular and scalable ATM switch using shared buffer architecture

Advances in VLSI technology have brought us completely new design principles for the highperformance switching fabrics including ATM switches. From a practical point of view, port scalability of ATM switches emerges as an important issue in the switch design. In this paper, we propose a practically implementable large scale ATM switch by integrating time-division and space-division switch architectures. We present a scalable shared buffer type switch and its expansion method.
