International bandwidth quota

I am currently working on setting up an Openstack cloud. Because international bandwidth is very expensive here, I would like to allow users to control the amount of international bandwidth available to them on an instance basis. Also, I would like to be able to measure actual international bandwidth used, so billing can take actual usage into account.

I have read through the quota documentation, but cannot seem to find any evidence that this is something that is easily achievable "out of the box".

I am keen to hear if anybody has any kind of input on how I might achieve this.

Have you taken a look at these links? Either create a new flavor with extra specs or use tc. Good luck.

Excerpt from link:

Network Traffic shaping -- i.e. limit inbound/outbound bandwidth -- is achieved by using tc. Note that libvirt uses tc to allow traffic shaping by network interface. If libvirt was using cgroups to control bandwidth, all network interfaces of a guest would be constrained since cgroups work at process level.

I have looked at those links, but I cannot see that any of those methods allow me to specifically limit international bandwidth for traffic moving through the same network interface. I could implement this limitation on gateway/switch level, but would like to control it from Openstack
