In order to enhance the fairness to TCP when packets are forwarded in the Internet

this paper presents the scheme of Highest-Rate-Flow Early Discard (HRFED) for buffer management

and researches its performance combined with FCFS and FQ scheduling algorithms.The EWMA weight in HRFED is proved analytically to control the margin of bursty traffic that will become highest-rate flow.By simulations based on different network scenarios

HRFED is proved to get better fairness than LQD

RED and TD(Tail drop)

and to maintain shorter average waiting time in the queue

as well as to keep high link utilization.
