How many documents? #9

Discuss how many documents (1,2 or 3) should developed:

As discussed during CCAMP IETF 112 meeting, we will have another update of this document and later discuss how to split it

Comment from @aguoietf :

If we look at the current flex grid and wson path computation - they are identical. Therefore I think a better strategy is to combine these two and have a common path computation model for both flex grid and wson. We can add flex-grid- or wson-specific constructs onto the common model using augments (or even within the same model by switch-case statement) if there is a need.

See: #18 (review)

The augmentations related with TE labels are not in common between WSON and flexi-grid models, but I would agree that all the other augmentations would be in common between WSON and flexi-grid models ...

An alternative approach could be to have a common l0-path-computation model with all the common augmentations to be further augmented by wson-path-computation and flexi-grid-path-computation models with the specific augmentations (most likely only those related to the TE labels)

Feedbacks from IETF 113 discussion:

https://notes.ietf.org/notes-ietf-113-ccamp

  1. Split the work in two documents: one for OTN (layer 1) and for WDM (layer 0): see issue #19 ;
  2. Try to merge WSON and flexi-grid path computation modules into a single module: see issue #20

I think we can close this issue
