SYSTEM AND METHOD FOR DYNAMICALLY UPDATING WEIGHTS OF WEIGHTED ROUND ROBIN IN OUTPUT QUEUES

A network device includes a group of queues, each having a weighted round robin mechanism. The priority queues on a port detect an overflow condition and transfer a flag to the weighted round robin device in response to detecting the overflow condition. The weighted round robin mechanism adjusts the weight associated with one or more of the priority queues in response to receiving the flag and transfers data from the queues based on the adjusted weights.
