Follow-on to IETF liaison: ‘Potential RTGWG work related to the disaggregated BNG architecture’

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
