Network congestion is caused by the unexpected burst.According to characteristic analysis of network traffic burst

the paper proposes a renovation method of congestion control algorithm(TCP-Shape) against the traditional congestion control algorithms

which uses dummy data segment probe to probe the available bandwidth in a TCP path and use flow shape techniques to make the flow look like more smoother.The experiments also show that the new congestion control algorithms can do better on data segment drop and throughout performance against the traditional congestion control algorithms.
