目前通信IP网网络性能评测方法主要有两种:一种是通过网管软件(例如群ping软件),另外一种方法是通过网络性能测试仪进行测试。两种评测方法原则上均是通过外部环境去评测网络性能。本文研究基于NQA技术的网络性能检测方法,通过在网络内部部署NQA测试用例,定期收集测试结果,从而提高评测网络性能精度。 At present, there are mainly two methods for evaluating IP network performance: One is through network management software (for example, group ping software), and the other is testing through network performance tester. In principle, both evaluation methods evaluate the network performance through the external environment. This paper studies network performance testing methods based on NQA technology. By deploying NQA test cases in the network and collecting test results regularly, the performance of network evaluation is improved.
