Tools for degrading my network connection? [closed

Question

I've written some applications than heavily use network, and I would like to test it over a slow network. I'm looking for a tool to simulate these kind of connections.

I'm only interested in Windows tools.

Answer 1

Throughput, latency, jitter, and packet loss can all impact user experience. Several software solutions that run on a host (or VM) allow these "levers" to be pulled.

Last time I researched I found a few possibilities:

Wanem

dummyet (link1) dummynet (link2)

nistnet

shunra (link1) shunra (link2)

tmnetsim tmnetsim

Cisco WAN-Bridge (CCO Login Required)

If you want something client based maybe try shunra, and if you want something in the infrastructure wanem is pretty easy since their is a VMWare appliance available.

Answer 2

Try dummynet. You will find lots of resources on the web, including this tutorial.

Answer 3

Dummynet is the way to go, especially if you want to simulate complex scenarios such as ADSL connections (asymmetric uplink and downlink), "Slow connection" (long latency), lossy links, etc. As Christian said, you can find some spare old PCs and install FreeBSD. You can also use VMware but I wouldn't recommand that.

Answer 4

What kind of network traffic? If it's HTTP this will work for you:
