中文摘要:

      对于AFDX这种新型航空数据网络系统，采用网络仿真技术对其进行实时性和确定性研究是非常必要的。实现AFDX系统的仿真，首先需要AFDX的网络仿真模型，建模成为了仿真系统实现的核心问题。在研究和分析AFDX系统及仿真需求的基础上，采用UML语言，并运用例图、类图、状态图和动态序列图建立了完整的AFDX网络仿真模型，并依据所建的模型实现了AFDX网络系统的仿真。通过仿真分析了AFDX网络端到端的时延和抖动，验证了AFDX网络的性能。

英文摘要:

      For AFDX which is a new type of aeronautic data network system,it is necessary to research its real-time and deterministic performance using network simulation technology.To simulate AFDX system,a simulation model of AFDX network is needed at first,therefore modeling becomes a primary key issue.After the AFDX system and simulation requirement researched and analyzed,using UML language,the whole simulation model of the AFDX network is established by case diagram,class diagram,state chart diagram and dynamic sequence diagram,and an AFDX network system simulation is realized with the established model.Through the simulation,the end-to-end delay and jitter of the AFDX network are analyzed and the AFDX performance is verified.
