[CCAMP] layer 0 type versioning

[Leeyoung <[e-mail]>]

Hi WG,

In the Prague meeting, in regard to ietf-layer0-type, the conclusion was converged toward having a separate draft for keeping ietf-layer0-types file from WSON topology draft (similar to what te-types did for TE topology/tunnel). As Italo suggested, I think it is sound to create different versions of ietf-layer0-types while the current version can move with WSON and Flexi-grid drafts. If we need change/add new grouping/parameters in the future, we can create a new version of ietf-layer0-types (with a new date, e.g.,  ietf-layer0-types@2020-10-10) to differentiate from the last version. This way, we can manage different versions of types file and avoid drafts from getting stuck with MISSREF in the RFC Queue.

So the action is to separate ietf-layer0-types from the WSON topology draft into a separate draft with a proposed draft name:  draft-ietf-ccamp-layer0-types (once rectified by the chairs). I will publish soon the two drafts (one for WSON topo and another for layer0-types). Please let us know if you have any comment/concern on this action.

Thanks,
