Abstract: This paper presents a fuzzy logic based ATM cell scheduling technique for input buffered non-blocking (ATM) switches. Simulation results indicate that such scheduling significantly reduces the average wait time for high priority cells when compared with single and multiple priority FIFO buffers. Simulations were run on an actual trace of ATM video cells generated by an ATM camera. These ATM video cells were multiplexed with other ATM cells from different sources. The reduction in wait time for high priority traffic is expected to improve the quality-of-service requirements at the communicating ends.
