For example, once an MPLS solution is deployed after a pre-deployment 
analysis or simulation which found an optimal LSP setup in which all LSPs 
have 50% utilization. If some LSPs have 80% utilization whereas other LSPs 
have 30% utilization in deployment.

Or, due to the dynamic nature of Internet traffic, some LSPs become 
congested while other LSPs are underutilized.  Maybe a LSP setup 
specifically for best effort traffic experience a large amount of traffic 
during the busy hours and that LSP become overutilized.

Does any drafts address this problem or has any solution been attempted or 
proposed in dealing with this issue?

Thanks.
Ray,
