摘要
通过分析AFDX(avionics full duplex switched Ethernet,航空电子全双工交换式以太网)网络协议标准、网络架构及端系统原理,提出了一种带宽分配间隔(bandwidth allocation gap,BAG)设定策略。根据AFDX网络性能指标和虚拟链路(Virtual Link,VL)性能指标,对该策略进行描述。通过MATLAB仿真平台对AFDX网络设计实例进行分析和验证,最终证明该策略能够有效地计算出带宽分配间隔设定值,提高了AFDX网络配置的效率。
By analyzing the standard of AFDX network protocol,network architecture and the principles of end systems,a bandwidth allocation Gap strategy was proposed. The strategy was described based on the AFDX network and Virtual Link performances. One AFDX network design example was analyzed and verified by MATLAB. Finally,the strategy was proved to be able to calculate the setting value of the bandwidth allocation gap effectively,and has improved the efficiency of AFDX network configuration.
