使用Fiddler模​​拟网络速度 [英] Simulate network speeds using Fiddler

问题描述

我正在使用Fiddler，并希望模拟不同的网络速度

I am using Fiddler and want to simulate different network speeds

是否存在可以使用延迟值模拟不同速度的任何已发布数据?

Is there any published data that I can use to simulate different speeds using the delay value ?

以下是Fiddler的默认代码，用于模拟56kb的调制解调器速度.

Following is default code of Fiddler to simulate 56kb modem speed.

if (m_SimulateModem) {
    // Delay sends by 300ms per KB uploaded.
    oSession["request-trickle-delay"] = "300"; 
    // Delay receives by 150ms per KB downloaded.
    oSession["response-trickle-delay"] = "150"; 
}

我想要256kbps，512kbps，1Mbps等的延迟值...

I want the delay values for 256kbps, 512kbps, 1Mbps etc...

推荐答案

这只是一个数学问题.

假设内容是立即可用的(例如，您正在从自动响应器中播放内容)，则唯一的延迟由 request-trickle-delay 和 response-trickle-delay 标志.

Assuming that content is available instantly (e.g. you're playing it back from the AutoResponder) then the only delay is controlled by request-trickle-delay and response-trickle-delay flags.

每秒有1000毫秒.

因此，如果您想将连接门控到每秒 1 兆字节，则将使用 1 毫秒的延迟.如果您希望将其控制为每秒 512 千字节，则请使用 2 毫秒的延迟.对于每秒 256 千字节，请使用 4 毫秒的延迟.

So, if you want to gate the connection to 1 megabyte per second, you would use a delay of 1 ms. If you want to gate it to 512 kilobyte per second, then use a delay of 2 ms. For 256 kilobytes per second, use a delay of 4 ms.

请记住，带宽通常以每秒位而不是每秒字节来度量.因此，如果您的目标是以每秒位数来衡量事物，则将每个值乘以 8 .

Keep in mind that bandwidth is often measured in bits per second rather than bytes per second. So if your goal is to measure things in bits-per-second, then multiply each value by 8.
