Abstract
A packet queueing system includes an ingress port configured to receive packets; queueing logic communicatively coupled to one or more egress queues for transmission via an egress port, wherein the queueing logic is configured to maintain an Acceptable Burst Size (ABS) token bucket which is set to enable absorption of microbursts, and implement a congestion avoidance algorithm to one of randomly drop packets and queue packets, wherein the congestion avoidance algorithm only performs the randomly drop packets responsive to the ABS token bucket being empty.
