基于Petri网理论的FC-AE-ASM建模与性能分析

摘要

以确定与随机Petri网为工具,基于周期消息,对光纤通道在航空电子环境的FC-AE-ASM(fiber channel anonymous subscriber messaging)网络进行建模仿真,根据仿真计算出FC-AE-ASM网络负载和系统的延迟时间两个重要的性能指标,通过对两个指标的性能曲线进行分析,有助于进一步理解航电系统事件消息在FC-AE-ASM网络中的传输机制,为综合航电系统的设计和完善提供重要的理论依据.%Based on periodic, this paper took deterministic and stochastic Petri net as a tool, to model a simulated FC-AE-ASM ( fiber channel anonymous subscriber messaging) network in the fiber channel avionics.environment.It also calculated two important performance figure of FC-AE-ASM network load and time-delay of the system according to simulation results.By analyzing the curve of the data, it is of help to gain a deeper understanding of the transmitting mechanism of event messages of avionics system in FC-AE-ASM network, and provide important theoretical basis for the design and improvement of integrated avionics system.
