摘要
通过分析AFDX终端系统关键技术,在AFDX网络虚拟链路的调度策略中提出采用自适应优先调度算法;并分析数据包在终端系统中的处理过程,进行网络演算建模,进而确定出AFDX网络针对不同类型数据的传输速率和服务时延。结果证明该算法较好地满足了航空电子网络数据传输实时性需求,并为AFDX智能网络管理模型中的参数模型和调度策略提供了重要的理论支持。
Through analyzing the key technologies in the AFDX end system, the adaptive priority scheduling algorithms is proposed for scheduling strategy in the virtual link of AFDX network. Different types of data transmission rate and service delay are determined in AFDX network after data packets analysis in the end systems process and network calculus modeling. The final results provide an important theoretical support for the parameter model and the scheduling strategy in AFDX intelligent network management model, and confirm that the adaptive priority scheduling algorithm can effectively reduce transmission delay for real-time data transmission in avionics data networks.
