Simulating Network Latency

[Guest]

Archived from groups: comp.dcom.lans.ethernet (More info?)

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?

Only Windows based software that I know of is Shunra's product.
