Hi all,
IMHO, neither current LDP nor current IP is capable to do loadbalancing.

Therefore, why don't we specify MPLS protocols which can establish 
QoS/Policy/Bandwidth-sensitive mp2p LSPs

and why don't we open a new IP routing WG which enables QoS/Policy/Bandwidth-sensitive IP forwarding ?

Shahram,

What are we comparing this against? IP? Please explain how in the IP world one
achieved IP vs non-IP load balancing and how it is different when you run LDP?
