A NEW PRIORITY CONTROL OF ATM OUTPUT BUFFER

A new ATM output buffer management strategy with priority control func tion is proposed, based on four types of cell classes. This strategy c an use system resource more effectively, meet the quality of service ( QOS) requirements (i.e, cell loss probabilities and delay characterist ics) of different services, and also can reduce the complexity of buff er. Furthermore, overload from lower priority traffic doesn't degrade the performance of higher priority traffic (i.e, cell loss rate and ce ll delay characteristics).
