+1, That’s what suggested in the blueprint a year ago: 
https://blueprints.launchpad.net/glance/+spec/transfer-rate-limiting

"It looks like consensus during summit discussion that rate limiting should be 
a separate facility running as a proxy in front of glance.”

Thanks,
Arnaud

Hi all,

I'm considering how I can apply image download/upload bandwidth limit for
glance for network QoS.

There was a review for the bandwidth limit, however it is abandoned.

* Download rate limiting
  https://review.openstack.org/#/c/21380/

Was there any discussion in the past summit about this not to merge this?
Or, is there alternative way to cap the bandwidth consumed by Glance?

I appreciate any information about this.

Hi Tomoki :)

Would it be possible to integrate traffic control into the network
configuration between the Glance endpoints and the nova-compute nodes
over the control plane network?

Yep, that was my first thought as well.  It seems like something that
would ideally be handled outside of OpenStack itself.
