Using Dummynet to emulate a narrow channel under Windows
Sometimes it is necessary to test the operation of the client application in network conditions close to combat. What when developing, what when choosing software. As a rule, the server is nearby, but you need to test both on such a channel and on this. Oddly enough, for a long time I could not find a convenient traffic shaping tool under Windows. From the searches I remembered: someone advised me to buy a modem for test purposes. You can put a Linux machine on the router and drive traffic on it, but this approach seems a bit excessive to me.
It turns out that at least a year in the Dummynet project there are binaries for Windows that allow you to easily and naturally control at least the channel bandwidth and latency.
Installs simply. For those who inattentively read Readme (like me), there is a guide on Youtube .
A convenient way to use it is described in the DummyNet article - HowTo {an open-source tool to tweak network latency and bandwidth} .
The lack of a graphical interface does not cause any inconvenience.
The only oddity is that the bandwidth is actually exactly 2 times wider than I write in the parameters, I have to remember about it. I checked (under Windows Vista) in three ways: by downloading the file, using the Windows network monitor and through SpeedTest.net .
This post was brought directly to the solution: DummyNet ~ Test Web / Network App by tweaking Network Latencies & Bandwidth. Thanks to the author. I can’t get enough.
