网络测试与故障查找

Network Testing and Troubleshooting

随着Internet技术和网络业务的飞速发展，用户对网络的应用需求空前增长，为了持续保障网络高效的运行状态，需要经常对网络的重要指标进行提取与分析，不断改善和提高网络的性能。网络测试的目标是及时发现网络瓶颈和潜在隐患，为优化网络配置和有效地进行网络性能管理提供可靠的数据支撑，对网络的服务质量指标进行量化、比较和验证。着重探讨网络测试的对象、方法以及如何利用网络测试技术查找局域网故障。

With the rapid development of Internet technology and network services, there is an unprecedented increase in the demand of the application of the network by its users. In order to constantly protect the efficient operation of the network, it needs frequent extraction and analysis of the important indicators of network to continuously perfect and improve its performance. The purpose of network testing is to detect its bottlenecks and potential problems, in order to optimize the network configuration and effective network performance management data to provide a reliable support and to quantify the quality of service indicators, to compare them and to verify them. This article focuses on the subject of network testing, as well as its methods and how to use its technology to locate the failures of local area network.
