Hi, WG & Chairs,

As a follow up of the virtual interim, the authors cleaned up the module & draft by updating the document. Now we believe the draft is ready to progress, please let us know the plan & advices.

BTW, the ietf-layer0-types was updated as well, and can be found at https://tools.ietf.org/html/draft-ietf-ccamp-layer0-types-06. It is suggested to cluster the two works together to proceed.

<tp>
I had a look at layer0 types and see  a number of quirks.

The YANG module references RFC4203, RFC7699, G.694.2 but I do not see them in I-D References or s.1.2

layer0 has become l0 in many places which looks like 'ten' on my screen.  Short is good in most cases but here, I wonder; I am conflicted about brevity v. legibility

wson-label-step text references teas te-types but not in the YANG; why? te-types has label-step int 32 but so what?

typedef dwdm-n is int16; is the range limited or are all values valid?

typedef cwdm-n ditto

typedef flexi-m ditto
'
channel-spacing can be alternated' puzzles me.  Alternate is often a bad idea as American and English usage varies but both seem wrong here

identity flexi-slot-width-granularity had a reference and then lost it and then had a reference and then lost it and next?

leaf min-slot-width-factor 
leaf max-slot-width-factor
is a constraint appropriate, such as min < or <= max?

RFC8363 is OSPF-TE which made me wonder if there was an equivalent for other IGP but AFAICT there isn't; is that right?

Tom Petch


Thank you.

Best wishes,
Haomian(on behalf of all authors & contributors)

主题: New Version Notification for draft-ietf-ccamp-wson-yang-25.txt


A new version of I-D, draft-ietf-ccamp-wson-yang-25.txt has been successfully submitted by Haomian Zheng and posted to the IETF repository.

Name:           draft-ietf-ccamp-wson-yang
Revision:       25
Title:          A YANG Data Model for WSON (Wavelength Switched Optical Networks)
Document date:  2020-05-19
Group:          ccamp
Pages:          60
URL:            https://www.ietf.org/internet-drafts/draft-ietf-ccamp-wson-yang-25.txt
Status:         https://datatracker.ietf.org/doc/draft-ietf-ccamp-wson-yang/

Diff:           https://www.ietf.org/rfcdiff?url2=draft-ietf-ccamp-wson-yang-25

Abstract:
   This document provides a YANG data model for the routing and
   wavelength assignment (RWA) TE topology in wavelength switched
   optical networks (WSONs).  The YANG data model defined in this
   document conforms to the Network Management Datastore Architecture
   (NMDA).




Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
