Hi Julien, Diego and Fatai, I support the idea of merging PCE requirements for GMPLS.
I also have a few general requirements from WSON PCEP application in the area of computing same wavelength (labels) for primary and secondary path computation. Lou indicated that this may be general enough to be general GMPLS requirement that can be applied to TDM timeslots, Ethernet labels and other labels including wavelength. Another requirement is bi-directional path and its label (wavelength assignment) for each direction. We should have ability to assign the same label or not in PCEP. I think this can be applied to TDM labels or others.
