Referenced liaison: Follow-on response to IETF liaison: ‘Potential RTGWG work related to the disaggregated BNG architecture’ (https://datatracker.ietf.org/liaison/1631/)

Body: Dear colleagues,
 
In our March 1, 2019 liaison “Follow-on to IETF liaison: ‘Potential RTGWG work related to the disaggregated BNG architecture’” (BBF LIAISE-281) we noted that the BBF started work on control and user plane separation for a disaggregated BNG (WT-459).   We are writing to give a progress update on our work.

- We have made substantive progress on the architecture and requirements for DBNG.
- The work has progressed well, but we would like to progress it a bit more before liaising a draft copy.
- We discussed the protocol to use and have a decision to pursue PFCP.
- We did note a distinct interest in S-CUSP from operators and vendors from China.

We will continue our work sending a preliminary draft of the document to IETF before publication.

Sincerely,

Lincoln Lavoie,
Broadband Forum Technical Committee Chair
