Liaisons referring to this one IESG follow-up regarding 'Potential RTGWG work related to the disaggregated BNG architecture'
Body
Dear colleagues,

Per our previous liaison on September 5, 2019, " Follow-on to IETF liaison: ‘Potential RTGWG
work related to the disaggregated BNG architecture’ "(LIAISE-339/Statements#1651) please
find attached a preliminary version of the WT-459 document which includes the BBF
Disaggregated BNG architecture, interface specification and requirements. These
specifications, among other considerations (e.g., protocol maturity), were used in the protocol
evaluation and subsequently the selection of 3GPP’s PFCP protocol noted in our last liaison.
The Broadband Forum will continue completing the work on WT-459 into 1Q2020 and will keep
the IETF apprised of progress.

Sincerely,
Lincoln Lavoie,
Broadband Forum Technical Committee Chair
