| Abstract: | To address the defects of industrial Ethernet in real-time-ness, it is proposed to make improvement on the mechanism of transmission protocol and the mechanism of real-time transmission with integrated graded scheduling for data services is set up to effectively reduce the delay of end-to-end data transmission. The Ethernet model, node model and process model of train backbone network and train set network are designed via OPNET tool. The parameters of the simulation are set according to the requirements of services and it has been verified that the delay of end-to-end data transmission can be effectively reduced by using the algorithms of integrated graded scheduling. |
