英文摘要：

To ensure the deterministic end-to-end transmission delay of high real time messages in SpaceWire networks, a design method of dividing the messages into time-triggered ones and event-triggered ones was proposed. By scheduling the time-trig- gered message＇s transmission time and the wormhole router＇ s working timeline, the control on the network＇s message transmis- sion was achieved, and a simulation system was designed and developed. Three types of network scenarios were designed, and by analyzing and evaluating the simulation results, the fact that the system combined the features of event-triggered and time-trig- gered networks was demonstrated. A network reconstruction scheme was proposed based on group routing, and the feasibility of the scheme was validated by simulation.
