Working Groups, This mail was sent on the mpls wg mailing list to trigger a discussion. It hs been pointed out that participants in other wg's might also be interested to contribute to this discussion. I therefore forward to the most likely wg's. Plese remember that the discussion is intended to take place on the mpls wg list (mpls@ietf.org). /Loa -------- Forwarded Message -------- Subject: [mpls] discussion on a common top for yang models related to MPLS Date: Fri, 5 Feb 2016 20:34:21 +0800 From: Loa Andersson <loa@pi.nu> To: mpls@ietf.org <mpls@ietf.org> All, We have had discussion among the MPLS, TEAS and CCAMP working group chairs - but as individual contributors, with chair half off. We agree that this discussion should be taken to the working group(s). The YANG models for MPLS and GMPLS are quite rapidly taking shape. MPLS and GMPLS technologies have traditionally been very close, but their development has been a bit disjoint. For the YANG models we would like to minimize duplication of models/work and think the structure should have a common the top, with specific technologies augmented below. The structure in general as well as the YANG model at the common top needs to be the generic and aligned across the output of at least CCAMP, MPLS and TEAS working groups. There has been good work progressing on TE specifics, e.g., see draft-ietf-teas-yang-te, but other areas remain. On the LDP side of the house draft-raza-mpls- ldp-mldp-yang is rapidly progressing towards working group adoption. The models defined in draft-saad-mpls-static-yang could serve as the start on filling some of the remaining gaps; covering core xMPLS definitions and static LSPs. There are a number of ways to make the structure intuitive and generic, and serve as a foundation for technology specific models. -- This effort can be viewed as the same type of work that was done for TE, see draft-ietf-teas-yang-te. We think it would be a good idea if the authors and the WG considers how to structure xMPLS definitions and static LSPs models to best foster common use across the different related models being worked on across different WGs. We are sending this mail in hopes of getting this discussion started.
