Re: [CCAMP] WG adoption poll on draft-dharini-ccamp-dwdm-if-param-yang-06

Daniele & Fatai, WG,

before replying to the WG adoption poll, I would like to raise a concern:

draft-dharini-ccamp-dwdm-if-param-yang-06 is IMHO opinion overlapping with draft-lee-ccamp-optical-impairment-topology-yang-01 that also defines a YANG model including
optical transponder properties (see https://tools.ietf.org/html/draft-lee-ccamp-optical-impairment-topology-yang-01#section-2.5 and the related YANG model attributes).

As there is a lot of interest in draft-lee-ccamp-optical-impairment-topology-yang-01 on the vendor as well as operator side ( we had weekly calls in the last weeks), the authors
are of the opinion that this draft shall also become a WG draft asap. This is something that should be discussed during the CCAMP session at IETF 104  in Prague.

The concerns are:

  *   How do we ensure consistency between the two drafts? The topology draft has a wider scope but deals with the same information contained in the if-param draft.
  *   The topology draft also defines 2 additional options to address optical transponder properties - the if-param draft only supports 1 out of 3 options!
  *   If draft-dharini-ccamp-dwdm-if-param-yang is defining a device model, an SDN controller must be capable to retrieve the information defined in the topology YANG
from the device in order to construct the topology. Hence model consistency is really a must.

Guidance from the chairs is appreciated.

Thanks,
Sergio and Dieter

Working group,

We finally managed to collect all the IPR disclosures and we’re ready to start the WG adoption poll for the dwdm-if drafts (YANG and LMP).

This starts a two weeks poll on making  draft-dharini-ccamp-dwdm-if-param-yang-06 a CCAMP working group document.

Please send email to the list indicating "yes/support" or "no/do not support" and a motivation for  your reply, mandatory for the "not support" and nice to have for the "support".

The polling will end on Monday March 25th ..

Thanks,

Daniele & Fatai
