Artificial Latency
-
I was asked by an acquaintance the other day how to produce latency on a virtual network. I was a bit at a loss. I assumed pfSense or VyOS could do this but now that I am looking that doesn't seem to be the case.
Anyone have an idea on how to introduce things like packet loss or latency into a virtual network?

I've always wondered how to "load" test things like network, RDS, Citrix etc.
(sorry no help I know

(sorry no help I know )There is a load testing suite for that called LoginVSI. It is the industry standard load testing system for that.

Good to know thanks Scott

Not sure what tools will just introduce some latency, though.
-
Some Bad QOS and throttling should.
-
What about some "hacking" tools like DDoS type stuff?
-
those things create noise and whatnot, but they don't simulate latency.

Why exactly would one ever want to introduce latency artificially?

Now else do you test to know how things will behave when there is latency?

Testing WAN applications on a virtual network. For instance figuring out how much latency an application can withstand before failing or corrupting data. Granted that doesn't make sense with the web based application but for a client-server application over a VPN it could be incredibly useful. The same could be true for bandwidth limiting and figuring out how much bandwidth an application requires to be reliable.

Yeah, I was wondering what you would be testing for. I guess that makes sense, seeing how much the processes can stand. But if you're adding some to test, then there must not inherently be any. You should be happy there's no latency and just not worry about it!

Like I said this would be more for WAN-esque applications. Running software over a VPN etc. I thought it would be a decent thought experiment.
