| 摘 要： | AFDX网络通过对传统的以太网技术进行改进,凭着其可扩展性,双冗余管理,通信网络延迟的可确定性等优越的网络通信性能,已成为新一代航空电子系统数据传输网络。文章根据AFDX网络带宽分配、网络延迟和虚拟链路抖动,基于消息驱动,以随机Petri网为工具对AFDX网络进行建模仿真,讨论了周期消息、事件消息对延迟时间的影响,通过性能指标分析,有助于理解消息在AFDX网络中的传输机制。

| Abstract: | Aim.The introduction of the full paper reviews a number of papers in the open literature and then proposes the research mentioned in the title,which,we believe,helps us to understand information communication,particularly the influence of periodic message and event message on the delay time of AFDX network.Sections 1 through 4 explain our research;its core consists of:(1) based on the AFDX network bandwidth allocation,network latency and the jitter of virtual links,we establish the AFDX(avionics full duplex... |
