AFDX网络分析及带宽分配间隔设定策略

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.Final-ly, 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.
