AT&T does provide coast to coast MPLS L3 VPN in the US.
AT&T supports 4 CoS and 6 CoS based on the QoS requirment.
Passive mode is available.

There are countries like China where Layer 3 handoffs are required.
For eg: China Telecom, China Unicom are certified and tested for QoS
capabilities as well.

If you have anymore technical questions you may unicast me.
