Tcp 吞吐量图答案

【问题标题】：Tcp Throughput GraphTcp 吞吐量图
【发布时间】：2011-06-09 06:24:36
【问题描述】：

我在 vb.net..m 的控制台上创建了一个 TCP 客户端/服务器聊天软件，该程序使用本地主机意味着数据包从同一个网络接口卡发送和接收。现在我在 Wireshark 上从这个软件中捕获了数据包。我想从 Wireshark 上捕获的数据中绘制 TCp 吞吐量图，但是我遇到了这个问题。请帮助我..！还教我在 x 和 y 轴上应该取哪个值..？

这是我在wireshark上捕获的数据，因为我无法区分发送和接收的数据包..！

抱歉，我找不到比这更好的方法来在这里发布我的wirehsrak 数据：-O

【问题讨论】：

如果您想绘制吞吐量图表，可以肯定的是其中一个轴将是“吞吐量”...

标签： tcp

【解决方案1】：

由于您正在监视您的 PC 与其自身之间的对话，是的，这将使其变得困难。一般来说，如果您是来源，那么您正在发送，如果您是目的地，那么您正在接收。

我建议 X 轴是时间，Y 轴是吞吐量。

【讨论】：

应该没那么难。您应该能够通过匹配wireshark报告的TCP端口号来识别客户端和服务器。
但是我在我的两个程序中都使用相同的 (9050) 端口..你想让我改变他们中的任何一个然后捕获packtes吗？
不，但是，这比如果您有 2 台测试机来验证您的想法更令人困惑，因为您为什么要监控流量与自己交谈？从技术上讲，它永远不会离开。端口号有帮助，但通常您肯定会查看 2 台不同的机器？
@ bug finder: x 轴是时间对我来说很有意义..但是我的wireshark数据中没有吞吐量这样的东西，如我的问题所示:-(
@Madiha：您在连接的两端使用相同的IP 地址和 TCP 端口？它是如何工作的？
