Re: [netmod] New Liaison Statement, "Liaison to IETF on YANG Models to enable G.fast deployments"

[Benoit Claise <[e-mail]>]

Dear all,

The NETMOD and NETCONF WGs thank you for referencing the work of the 
IETF and contributing to the drafts you mention through the IETF 
process. This is by far the best way to complete the work in a timely 
manner and continues to foster the open and cooperative working 
relationship between the IETF and the Broadband Forum.

In the mean time, the two drafts you note became WG documents: 
draft-ietf-netmod-entity and draft-ietf-netmod-intf-ext-yang-00. We 
encourage you to follow progress on data tracker 
https://datatracker.ietf.org/doc/draft-ietf-netmod-intf-ext-yang/ and 
https://datatracker.ietf.org/doc/draft-ietf-netmod-entity/ and through 
the participation you have noted.

Regarding your interest to work on "forwarding/QoS and required 
protocols (e.g. layer 2 multicast model & DHCP)", please note that there 
are already a couple of forwarding related YANG data models, mainly L3 
forwarding. There is also a QoS related YANG data model, 
draft-asechoud-netmod-qos-model, which we believe could become a WG 
document. And finally, a YANG multicast design team, 
https://trac.tools.ietf.org/wg/pim/trac/wiki/yang, focuses on producing 
PIM and IGMP/MLD YANG data models. Please work with the respective 
contributors so that the layer 2 specific data model aspects nicely fit 
in the overall data models.

If you have interest in other related IETF work please don't hesitate to 
let us know.

Please continue to keep us apprised of your work noted.

Regards, Benoit (OPS AD)

> Body: The Broadband Forum is developing YANG models to meet the end 2016/early 2017
> G.fast deployment timeline announced by several service providers. Broadband Forum
> practice is to base its YANG work on existing IETF YANG models and expertise.

> In the Broadband Forum meeting of 18-22 April, the Fiber to the Distribution Point (FTTdp)
> Work Area agreed to work on developing YANG models based on draft-entitydt-netmodentity
> & draft-wilton-netmod-intf-ext-yang for G.fast deployments meeting the above
> timelines. Given our interest in these drafts, participants will work within the IETF

> Further, we would like to inform you that our FTTdp Work Area is defining YANG models
> for Broadband Forum specific context and use cases for :
>
> - forwarding/QoS and required protocols (e.g. layer 2 multicast model & DHCP)
> - bulk data collection (evaluating draft-ietf-netconf-yang-push and related work),
> - software image management,
> - operational states (evaluating draft-ietf-netmod-opstate-reqs and related work)
>
> Once the models reach a level of maturity we plan to share these with IETF for review and
> comment. Comments from IETF may be made via a liaison or BBF members may
> comment directly.
