Hi Cyril,

Objective functions for GCO contexts and others are definitely an optional requirement for PCEP extension for RWA. In the past, the PCE WG had one objective function draft separate from PCEP draft. So my inclination is to ask the PCE WG if this requirement should be a part of this draft or to separate this work into a new item. I will include this OF requirement in the revision, which will shortly be published. 

Thanks,
Young

Hi, 

Please find attached a proposal on the outline and text regarding a RWA aspect we did not consider up to now :   Spectrum optimization 
Flexigrid discussion brought this in the light but this is a fundamental DWDM RWA aspect, which can be best addressed IMHO by Objective functions,  Which will fit also nicely into the GCO context. I thinks it a better solution to draft-zhaoyl-pce-flexi-grid-pcep-ex.

I think that at least we should have some indication that standard DWDM has already two spectrum and the assignment should already be considered, Simply by taking the case of a 100Ghz grid : the spectrum can already overlap with 50Gh (and smaller grids) .

Your comments/refinement are welcomed.
