Thank you for reviewing this.  

I had not appreciated that 'Reserved(CTc)' is actually a normalized quantity, normalized by the 'LSP/link size overbooking multiplier' (LSOM).

Just to further clarify, in terms of the actual bandwidth requested, I suppose this relationship must hold:

Reserved(CTc) = Bandwidth-Requested(CTc)/LSOM

where

Bandwidth-Requested(CTc): For a given Class-Type CTc ( 0 <= c <= MaxCT ), define "Bandwidth-Requested(CTc)" as the sum of the bandwidth requested by all established LSPs which belong to CTc. 

Is that correct?  If so, then 'Reserved(CTc)' is also a 'normalized' quantity, but this time it is normalized by the LSOM, right?

Thanks for the clarifications,
Jerry
