摘要
航空电子全双工交换式以太网(AFDX)已成为现代先进民用飞机通信网络的主干网络,AFDX网络的可靠性对于航电系统至关重要,研究其可靠性评价方法有着重要的意义。阐述了AFDX网络连通可靠性的评价度量参数与模型,研究了蒙特卡洛仿真模型、参数和算法。最后给出双余度级联AFDX网络连通可靠性的仿真计算结果。
The avionics full cation network in advance c duplex switched Ethernet （AFDX） has been selected as backbone communi- ivil aircraft. And, its reliability is crucial to avionics system. So, it is signifi- cant to study its reliability estimation. This paper expounds the measurement parameter of reliability esti- mation of AFDX network connectivity and network model. Then, we studied the model, parameters and al- gorithm of Monte Carlo simulation. Last, this paper gives the calculation results of reliability of double re- dundant cascade AFDX network connectivity.
