I am not talking about policing in the core, I am talking about 
detection in the core.

Policing at the edge is pretty standard. You can police a 50Gbps EoMPLS 
flow coming in from a customer port in the edge. If you've got N x 
10Gbps links in the core and the core is unable to detect that flow in 
depth to hash it across all those 10Gbps links, you can end up putting 
all or a good chunk of that 50Gbps of EoMPLS traffic into a single 
10Gbps link in the core, despite all other 10Gbps links having ample 
capacity available.

Do you operate a large scale IP/MPLS network? Because I do, and I know 
what I see with the equipment we deploy.

You are welcome to deny it all you want, however. Not much I can do 
about that.

Mark.
