We investigate packet discarding schemes for TCP over ATM with GFR service. We test the throughput, fairness and goodput of two existing schemes, EPD and DFBA. In the simulation, we find that goodput is low when the network is incongestion. To provide a solution for this problem, we propose the SWFA(Selective Weighted Fair Allocation), which discards packets from selected sessions rather than by probability. Our results shows that SWFA achieves throughput and goodput enhancement over other schemes.
