摘要
网络性能的实时监测已经成为一项必要的工作,网络性能测试终端正是这样一种设备。用嵌入式系统实现网络测试终端是一个理想的选择。文中介绍了一种以若干个测试终端组成一个测试网络来监控网络性能的方法,具体分析了嵌入式网络性能测试终端的软硬件设计,利用GPS解决多个测试终端时间同步的问题。给出了修改操作系统内核以获取高精度时间和文件系统设计及配置的方法。
It is necessary to real-time monitor the performance of network, and the network performance monitoring terminal is such kind of device. The embedded system design is ideal approach. This paper introduces an arrangement of several terminals working together to monitor the performance of network, analyzes the hardware and software design for the monitoring device, time synchronization by GPS receiver. Modification of OS kernel needed to support high time resolution, and configuration of file system are also included.
