Research on the TCP congestion control slow start algorithm improves the end-to-end bandwidth measurement on real-time line. The TCP congestion control slow start has a problem that the send-velocity change is great and the capability of the network is low. This paper analyses the limitation about the improved slow start algorithm and end-to-end delayed bandwidth model, then advances the end-to-end available bandwidth measurement methods and realizes an improved algorithm of phase-divided smooth slow start based on the bandwidth measurement, and gets a flexible slow-start parameter model, real...
