The research on transmission of networked control based on high speed Ethernet

Along with the improvement of real-time property and certainty, its usability in increased in network control system. This paper analyses the feature of high speed Ethernet and cause of network delays. The feature of network control system´ data for transmission technology is researched on this paper. A protocol based on UDP is proposed to carry out the transmission of network control data of high speed Ethernet. This protocol meets real-time property and certainty requirement of short data in transmission control system. Simulation experiments show the validity of this proposed method.
