Abstract: Depending on excellent performance, fiber channel becomes an inevitable choiceof avionics network in next generation. But the message dispatching form of event triggered limit analysing on the performance of the avionics system, in order to increase the time determinacy of message in network, basing on the time triggered protocol, a kind of message scheduling algorithm of time triggered is presented to FC. By means of the switched network modeling, using a method of theory and simulation are combined to analyze the FCFS scheduling algorithm and the time triggered scheduling algorithm, the results show that the time triggered scheduling algorithm can improve the deterministic effectively for network message, meet the request of avionics system security key message transmission.
