Similarly, it compares the average sending rate of effective packet of the two algorithms, When the channel rate are 5 Mbps and 40 Mbps, corresponding the average sending rate of effective packet of BEB algorithm are 0.610E5 BPS and 3.8710E5 BPS, but the average sending rate of effective packet of the improved algorithm are 1.010E5 BPS和4.4810E5 BPS.
