Hi Paul I think this flavor bp is related. https://review.openstack.org/#/c/90070/ By using flavor, you can specify the flavor for routers ( high bandwidth or low bandwidth ) such as VM (vCPU vMemory etc). I don't see any bp for flavor based scheduling yet, but IMO it is great we could have such scheduler such as Nova's filter scheduler.
