Abstract�� High speed data bus technology is one of the core techniques in avionics. IEEE-1394 is a serial high speed data bus, and has been applied in avionics successfully. Its asynchronous transfer mechanism guarantees the reliability of data transferred and is widely used to transfer command and status data. To solve the problems of transmission delay, throughput and bus utilization in IEEE-1394 bus asynchronous transfer, IEEE-1394 asynchronous transfer model was developed based on deterministic and stochastic Petri nets (DSPN). Furthermore, the asynchronous transfer performance was simulated by means of the established model. Through simulation research, the relationship between IEEE-1394 asynchronous transfer system-s throughputs, average waiting time and packet size, packet arrival rate was obtained. The computation method for the limitation of IEEE-1394 asynchronous transfer packet arrival rate also was given.
