摘要
针对如何准确地刻画和描述网络化测试程序请求行为的问题,建立了网络化测试业务流模型;在分析LXI测试系统通信协议和测试程序的基础上,明确了测试业务数据的结构、种类及各类数据的到达特点,然后以此为基础,对各类业务数据分别建立了到达模型,并提出了模型参数估计的方法,最后利用OPNET实现了测试业务流的模拟,验证实验结果表明该模型正确;该模型为进一步研究测试业务特性和系统实时性能分析评价奠定基础。
In order to accurately describe and depict the networked TP request, networked testing traffic is modeled. After analyzing the communication protocol and TP of LXI test system, the structure, types of testing data and their arrival characteristics arc made clearly. Then, on this basis, their arrival models are established, and the parameter estimation method for them is advanced. Finally, simulate the testing traffic by OPNET, and through the comparison of simulated and measured data, verify the testing traffic model is correct. It lays the foundation for the further study of testing traffic feature and real--time performance evaluation of the system.
