PushOut (PO) queue management scheme is capable of fair buffer utilization and good loss performance, but it is possessed of high implementation complexity and poor protection against short-term burstiness of lightly loaded flows. To improve above drawbacks, a simple but efficient scheme, Pushout with Differentiated Dropping (PDD), is proposed in this paper. The authors design a weight function to estimate the weight of each active flow according to corresponding traffic intensity, which provides discriminative packet treatment when the buffer is full.
