The Broadband Forum is interested in utilizing the IPFIX protocol to support
bulk data collection within its Access Node specifications. As part of these
efforts, the Broadband Forum previously reviewed the current YANG data models
available for IPFIX / Packet Sampling, specified in RFC 6728.

The Broadband Forum is aware of IETF
draft-boydseda-ipfix-psamp-bulk-data-yang-model which defines a YANG model for
packet sampling (PSAMP) and bulk data collection and export via IPFIX. This
model conforms to the Network Management Datastore Architecture (NMDA) defined
in RFC 8342 and replaces the model defined in RFC 6728.

We would like to inform the IETF that the Broadband Forum intends to make
normative reference to this document as an integral part of its specifications.
To that end it would be advantageous for the document to be pursued as a
Standards Track document.

Specifically, it is our intention to normatively reference this in future
revisions of the following BBF technical specifications: •       TR-301 –
Architecture and Requirements for Fiber to the Distribution Point •      
TR-352 - Multi-wavelength PON Inter-Channel-Termination Protocol (ICTP)
Specification •       TR-413 - SDN Management and Control Interfaces for
CloudCO Network Functions

As such there is a strong desire to see it progress through the IETF process to

Your consideration is greatly appreciated.

Lincoln Lavoie,
Broadband Forum Technical Committee Chair
