摘　　要：分组延迟极大地影响了网络应用的整体性能 ,确定延迟的原因和位置至关重要 .R.Caceres等人提出了比其他网络性能测试与分析方法要好的端到端基于组播的网络性能测试与分析法 ,但这类方法还有一些不足之处 .主要从减少测试分组数和降低计算复杂度两个方面改进了该测试分析法 ,从而既减轻了带给网络的负载 ,又使测试分析更加高效、适用 .实验结果表明 。Packet delay greatly influences the overall performance of network application, so it is very important to identify the cause and location of delay. Among the many performance measurement and analysis methods, the multi cast based inference method advanced by R.caceres etc. is better than others. But it still has some shortcomings. In this paper, a progressed method is advanced, it reduces probes and has lower time complexity, so it not only reduces loading brought to network and is more efficient. Experiments results showed that the method in this paper is more efficient to capture the delay distribution.
