Abstract�� To solve real-time performance evaluation problem in fibre channel (FC) network, a network model of the FC networks was built, and then two different switch strategies were proposed to satisfy different needs of avionic networks. A method of end-to-end maximum delay calculation was provided, based on network calculus analysis theory. Delay upper bounds based on the strategies of switches were analyzed. The analysis results show that using non-preemptive priority (NPP) service strategy, compared with first come first service (FCFS) service strategy, can reduce the upper bound delay of high-priority data stream. Finally, the evaluated method was testified by the simulation results on OPNET.
