） Abstract： This paper is to study how to acquire the data package transmissed by applications which are based on TCP and UDP protocal
In order to further processing the data package, including bandwidth control, time delay control, error rate control etc
This goal is achieved by replacing the based service providers of system and hooking the WINSOCK2 SPI
After successful interception, achieving the precise control to the specified port bandwidth and error rate is another target
A new algorithm based on traditional leaky bucket algorithm is proposed
Comparing with the other methods, the method mentioned in this paper has many advantages, like improving the efficiency of development, precise interception and good portability
Thus it has a more widespread application space
