如何在OMNET++中获取丢包率(%)、吞吐量、E2E时延统计信息？

Question

我已经尝试过@statistic[nameOfStatistic]来计算PacketLoss，但它仍然没有出现在.anf中。如何计算它？我无法找到足够的信息。请帮忙！

我应该使用哪个模块过滤器或结果名称过滤器来获得所需的结果，即丢包吞吐量和 E2E 延迟（所有这些分别针对每个节点）？

我已经浏览了 stackoverflow、文档/手册和 google groups。

谢谢你。

我已经检查了您的模拟：

numHosts=3
numWHosts=3
time of simulation: 36 s

结果确实包含您的 NED 统计数据中指定的内容，即

endToendDelay

和

throughput

。

看到他们：

• 进入目录

  results

• 双击任意 *.sca 文件并确认创建新分析文件 (*.anf)
• 选择底部的

  Browse data

  ，转到

  Vectors

  选项卡
• 在字段中

  result name filter

  写下

  endToEndDelay*

您应该看到记录的矢量：

双击任意行后，将绘制统计数据，例如：

当您在

throughput*

中设置

result name filter

时，您将看到吞吐量的统计数据：
