Simulating Network Latency

Been looking for a program that can simulate network latency. We have a problem with an embedded controller, that seems to suffer from network latency. Most of our clients are using networks that feed from a Mfg plant to a corporate network. We are afraid that the delay is significant, and that our application times out.

I have seen "DUMMYNET", for Linux. I am basically looking for a Windows solution. A multihomed PC or Laptop, running software that can slow down (add delay) to packets. WE want to test inhouse.

Let me know if you know any programs.

Thank you

It's not very difficult to write such a thing, I hacked up a traffic generator in C under DOS a few years back using the packet interface, which does most things you need. Besides, if you develop it yourself, it's trivial to add features...

I am not aware of a free windows solution.

Installing linux sounds easier to me that writing the code.

There are commercial solutions. Maybe you could hire one.

Maybe DummyNet is for FreeBSD?
