What tools are available on Windows to simulate/emulate network issues?

  • 772

I am looking for tools for Windows that can act as a reverse-proxy in front of a server to introduce various networking issues like jitter, delays, or packet loss.

My preference is a software solution that will work on Windows. Httpd mod_proxy doesn't appear to support such a configuration, and googling for a tool in this category is proving fruitless.

    clumsy makes your network condition on Windows significantly worse, but in a managed and interactive manner.

  2. If you're just testing how your app will repsond to ill-behaved networks, you could do worse that fire up a linux box in front of it with Wansim - I know, you wanted something ON the windows box... but probably doing the delayage there is an unfair test, as you've already bypassed a bunch of the stuff that is under test (eg how the OS & hardware handles packet loss).

    I think you're not going to find web proxies to induce this sort of nastiness - far too high level.

    Apologies if "testing your app's resilience" is not what you are after... thought i'd make an assumption rather than ask and forget to reply ;)
