Recently with the development of high-speed railways, the traditional train communication network (TCN) can barely meet the increasing demand of realtime and high data rate transmission requirements. In this study, a solution based on switched Ethernet is firstly proposed with reconstructed TCN topology and communication protocol stacks. Then, virtual link and flow shaping were introduced in order to realize a strictly real-time communication. By using the network calculus theory the presented strategies were proven to admit a maximum delay constraint and simulation results also verify our analysis. Finally a detailed analysis of the vehicle layer and backbone layer are given, where the results show that traditional TCN could be replaced by TCN based on switched Ethernet.
