摘　　要：该文研究FC-AE-ASM(Fibre Channel-Avionics Environment-Anonymous Subscriber Messaging,光纤通道-航空电子环境-匿名订户消息)网络的数据发送控制问题。从FC-AE-ASM网络的基本原理出发,提出了基于时间片轮转的数据发送控制算法,推导出在该算法下数据集合严格实时的充分必要条件,以链路占用率为性能衡量指标,证明在最差条件下,采用该算法后FC-AE-ASM网络的实时性可以得到保证。最后采用OPNET进行了仿真,通过结果分析,说明了理论分析的正确性。This paper studies the data transmission control with FC-AE-ASM （Fibre Channel-Avionics Environment- Anonymous Subscriber Messaging） network. The periodic task model in real-time communication is adopted. Based on the basic principle of FC-AE-ASM network, a data transmission control scheme is proposed based on the time slice rotation. The necessary and sufficient condition of guaranteeing data deadlines under the data transmission control scheme is derived. Taking the achievable link occupation ratio in the worst case as the main index, the superiority of the control scheme is also derived and finally tested with OPNET simulation results.
