目前民机航空数据网络系统,一方面逐步走向了高度综合化,一方面由于飞机航电功能承担飞机先进性要求,业务量也在逐步增大,因此导致了网络系统愈加复杂,这就对网络优化设计提出了新的要求。针对于此,该文论证了网络建模仿真手段,作为民机机载网络的设计论证与确认工作手段的重要性,同时,针对目前常用的几类网络仿真技术的特点和适用性,进行了分析、比对和总结,并针对一种目前可行的网络仿真的具体实施用例进行了详细阐述。
At present, the civil aviation data network system is gradually becoming highly integrated. On the one hand, as the aircraft avionics function takes the advanced requirements of the aircraft and the traffic volume is also gradually increasing, it leads to the more complicated network system, Optimized design made new demands. In view of this, this article demonstrates the importance of network modeling and simulation methods as a means to demonstrate and confirm the design and verification of on-board network of civil aircraft. At the same time, in view of the characteristics and applicability of several commonly used network simulation technologies, Analyze, compare and summarize, and elaborate on a practical implementation case of a currently feasible network simulation.
