To reduce the effect of the unreliability of UDP communication on the test of the network servo system, this study aims to propose an improved method by adding data preprocessing layer between the application layer and the transport layer on the basis of the UDP communication. According to the different functions of the sender and the recipient in the communication, different improvements are used for the data preprocessing layer. In the case that one or two data packets may be lost, the extrapolation algorithm embedded in data pretreatment layer will be used to extrapolate the lost data packets. The simulation results show that the improved UDP communication can not only improve the reliability of data transmission, but also timely extrapolate the lost data packets when they are lost, which meets the requirement of high real-time capacity for the servo test system.
