Modeling and Performance Analysis of FC-AE-ASM Switched Network Which Based on PETRI Net Theory

摘要:

JP+1]新一代航空电子系统从结构上发生了变化,机载系统资源的共享程度越来越高,FC-AE-ASM(fiber channel-avionics environment-anonymous subscriber messaging)协议作为新一代的高性能网络通信协议被引入到航空电系统中;从FC-AE-ASM协议、交换机工作原理出发,以Petri网为工具,建立起网络结构模型、消息传输模型及交换机的工作原理模型;对所建系统模型进行仿真,可得出网络负载和消息延迟等性能指标,通过对性能指标的分析,为光纤通道网络在航空电子环境下的应用提供重要的理论依据。

Abstract:

The structure of new generation avionics systems has changed, sharing degree of airborne systems resources become higher and higher. FC-AE-ASM(The Fiber Channel-Avionics Environment-Anonymous Subscriber Messaging) protocols as high-performance network communication protocols of new generation was introduced into the avionics system. This article starts from the FC-AE-ASM protocol, the principle of switch works, with Petri-nets as a tool to establish a network model ,message transmission model and switch works working principle model.Do simulation to system model which have built,can obtain results of network load and message delay performance trend indicators,through the analysis of the performance trend indicators, provide important theoretical basis for fiber channel network applications in avionics environment.
