Abstract

"An ATM switch with distributed cell scheduling is proposed in this paper. By using a crossbar switching structure with large buffers at input ports and small buffers at each crosspoint, the cell scheduling is distributed at input and at crosspoint buffers. The discrimination of incoming cells into service classes at input buffers, and the use of a modified virtual output queuing (VOQ) technique provide, to the proposed switch, facility to satisfy easily the QoS and a throughput of 100%. An example of performance analysis based on priority service classes is carried out and the results show a very promising ATM switch."
