Abstract

In this paper, we present a novel design concept for constructing high-speed output port codrollers for ATM switches, and statistical multiplexers. The newly proposed concept provides an external framework in which the internal hardware designs can be modified to achieve a specific quality of service. Two distributed control designs are provided, namely the fully shared buger and partially shared bufler architectures. The fully shared buger architecture can provide the pushout mechanism or complete bufer sharirrg queueing discipline which gives the best loss and delay performances for incoming cell stream with static priority.
