Is it possible to configure a Windows machine's networking stack to mimic internet delay and upstream bandwidth limits?

 

Edit:

netsh interface ipv4 set interface "Local Area Connection" latency=50 upstreamlimit=2000000 downstreamlimit=10000000

OR

netsh interface ipv4 set interface "Local Area Connection" crawlliketheinternet=enabled

You have to modify a Javascript file to dial in exactly what speed you want to simulate, but it works pretty well. There are also some plugins for fiddler out there with a more complete feature set.

Maybe a combination of things would work.

        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"; 
        }

So it seems to apply a delay based on the volume of data.  That seems reasonable for throttling bandwidth.

Plus this Fiddler Extension http://fiddlerdelayext.codeplex.com/ for latency looks like a winner combination.
