The TCP congestion control slow start has a problem that the send - velocity changes great and the capability of the network is low. This paper analyzes the limitation about the improved slow start algorithm and end - to - end delayed bandwidth model, and realized improved algorithm of phase - divided smooth slow start based on the bandwidth measurement, and got a flexible slow - start parameter model, realized the auto - adaptation parameter setting. The simulation results show that the lost probability of multi - packet in the congestion windows have great dec...
