Fair question. So, let's poll for an answer before we put it in the 
requirements draft:

Considering a DS-TE solution which allows to enforce different overbooking 
ratios for different Classes of Service, are there Network Operators out 
there (I repeat *Network Operators*) who have a specific requirement for 
enforcing different values for these per-COS overbooking ratios in 
different parts of the network ?


Thanks
