MPLS signaling

I think this depends on the network. Most major tier 1 public IP backbones
do not necessarily run QoS through the core. MPLS in these networks is used
for traffic engineering such as constraint-based routing and dynamic LSPs.
Private MPLS-based networks may (and do) use dynamic QoS signaling. Maybe
someone who maintains one of these networks could chime in.

So most people do manual QoS/bandwidth provisioning ?
I'm looking into this for L2 over MPLS VPN (Martini draft).
Thanx
