基于镜像口抓包的数据采集记录系统设计与实现

在系统研制试验过程中对数据进行采集记录，不仅可以为系统功能性能评估提供数据源，也可以为重现战场试验态势提供手段。本文针对此问题及工程中的实际需求设计了一种基于分布式时间机制、网络监听、数据抓包和多缓存记录等关键技术的数据采集记录系统，该系统设计包括系统组成与架构和关键技术的设计与实现。最后根据设计内容进行了仿真应用，针对系统研制试验过程中的性能指标进行了测试和分析，结果表明该数据采集记录系统不仅运行高效， 且能够很好地满足系统研制试验阶段的要求。

Design and Implementation of Data Acquisition and Recording System Based on Capturing Packet Through Port-Mirroring

Collecting and recording data during system development and testing can not only provide data sources for the performance evaluation of system function, but also provide a means for reproducing the battlefield experimental situation. In the paper, based on distributed time mechanism, network monitoring, data capture, and multi-cache recording, a data acquisition and recording system are designed for the actual needs in projects. The system design includes the system composition and architecture, and the design and implementation of key technologies. Simulation application was carried out according to the design content, and the performance indicators during the system development test were tested and analyzed. Experimental results show that this data acquisition and recording system not only runs efficiently, but also satisfies the requirements during the system development test stage.
