I think I've discussed things like this a few times in the past and pointed to a system implementing something similar.
Something similar was deployed by Comcast in the United States, using a combination of in-house developed software and Sandvine hardware.
To accomplish this on the VM network would require considerable integration work, it would be a long way from being a trivial exercise.
The current system is largely out of the box, as is its' configuration looking at the balls up that has been made of it
It could be fine if implemented properly, which it has not been. Shaping should be monitored
very closely during implementation. This looks like it was configured by an IP engineer or Sysadmin who went on a couple of courses and knows how to configure the stuff but has no idea why he's configuring it that way as he's not an actual application network engineer and is not familiar with the applications he's trying to throttle.
If he were people wouldn't be able to dodge shaping by changing port they run applications on.
Pretty weak to be honest and not a patch on Plusnet's intricate, generally accurate and well controlled systems.
