One difficult problem in the current Internet is how to guarantee the Quality of Service (QoS) for each connection. This paper proposes an adaptive scheduler for input-buffered switches to improve QoS guarantees for various traffic classes. The algorithm introduced in the scheduler is based on the required bandwidth of each connection. Our scheduler uniformly deals with various traffic classes without any strict priority discipline. Thus, it can effectively use the residual resources of the switch for any traffic pattern without facing resource starvation. Prom simulation results, it is clarified that the proposed scheduler has better performance, in terms of throughput, packet delay and deviation, than some well-known schedulers.
