摘要
AFDX网络由端系统、交换机和传输链路组成,交换机是AFDX网络的中枢构件。本文首先研究了AFDX交换机的功能和性能,在此基础上,设计了AFDX交换机测试分析系统,测试软件基于多框架、多视图、单文档,采用面向对象技术实现了交换机配置文件的处理、数据帧的捕获和解析、VL转发特征测试、技术时延测试、流量管制测试等一系列功能。最后进行了测试分析试验,试验展示了该测试分析系统对于AFDX交换机的测试效果。
AFDX network consists of end system, switch and transmission link, and AFDX switch is the key component of the network. Base on the research of the AFDX switch, a system was designed to test and analyze AFDX switch. Based on the object-oriented method, testing software was programmed to handle switch configuration files, capture frames, test switching feature, technology delay and flow policing feature of AFDX switch and demonstrate the testing results. An example for the testing and analyzing of AFDX switch was given, and the performance shows the validity of the system.
