Hey Julian

"tc" is your friend.

For UDP, you may also need some iptable mangling.

We're looking for a good way to simulate both bandwidth and, critically, latency situations for VDI connections. Bandwidth is easy but I'm struggling to find a nice neat way, or affordable software, to simulate different latency times for anything other than ordinary web TCP traffic.
HP RGS for instance uses a custom return port range (one socket per session) which none of the traditional tools can handle. In addition it's UDP which most dont handle too.
Has anyone else needed to / tried to do this for your own remote VDI deployments?

In the mean time, our network architect found this:https://www.itrinegy.com/products/network-emulators
Clumsy looks very cool though, thanks Ken!
It's a win environment at both ends so tc helps not.

If youre testing Teradici or anything else that relies on hardware, a WAN emulator is probably your best bet. If you go the eBay route, Anue and Apposite both have emulators available but be mindful of licenses and speed. Some emulators look good but may be limited to 10Mb or 100Mb.
