Purpose For information
Attachments BBF LIAISE - 266 - LS to IETF on IPFIX YANG
The Broadband Forum is very interested in utilizing the IPFIX protocol to
support bulk data collection without packet sampling requirements within our
fiber to the distribution point (FTTdp) specifications. As part of these
efforts, the Forum has reviewed the current YANG data models available for
IPFIX / Packet-Sampling (ietf-ipfix-psamp, RFC: 6728). This module appears to
support configuration of IPFIX/psamp as a single entity, which is not easily
separated into the transport protocol (IPFIX) and collection item
(Packet-Sampling) “components”. We believe this will make it difficult to
extend the existing model to support the bulk data collection requirements.

The Broadband Forum would like to get the opinion of the IETF Ops Area on the
best approach to extend the YANG models to support use of IPFIX for bulk data

We look forward to your feedback on the desired approach and would be happy to
support these efforts in any way possible. The members of Broadband Forum are
ready to begin working on this effort. Ideally, we would like the work to be
concluded by mid-2019.


Lincoln Lavoie,
Broadband Forum Technical Committee Chair
