Abstract

See full text

A novel method of servicing multiple data queues having different priorities is provided in a network switch. A dequeuing logic circuit services the data queues in a round-robin fashion. Programmable number of data packets is selected from each data queue in each cycle. The dequeuing logic circuit compares the number of data packets selected from a current data queue in a current cycle with the preprogrammed number of data packets set for the current queue, and selects a data packet from the current data queue only if the number of packets selected from the current data queue in the current cycle is less than the preprogrammed number. Selection of a data packet from the current data queue is bypassed, processing a next data queue, if the number of packets selected from the current data queue in the current cycle is not less than the preprogrammed number.
