developed to assist in TCP Parameter Optimization, but here we do not want to study the TCP Window Scale and maximum segment length, because this is not the focus of our current discussion. However, when testing a high-throughput AP, you may find it necessary to tune TCP parameters so that you can get a larger throughput on each iPerf client-For details, see DrTCP.
