Follow-on response to IETF liaison: ‘Potential RTGWG work related to the disaggregated BNG architecture’
IESG follow-up regarding 'Potential RTGWG work related to the disaggregated BNG architecture' |
Body |
The IETF has received two liaison statements from the BBF related to the disaggregated architecture for the fixed network Broadband Network Gateway described in TR-384. (https://datatracker.ietf.org/liaison/1566/ and https://datatracker.ietf.org/liaison/1600/). The Routing Area Working Group (RTGWG) within the Routing Area of the IETF has been discussing a set of proposals for protocols to realize the separation of control and user plane for the disaggregated BNG architecture for fixed network subscribers. We recognize that the creation of protocol specifications to support the disaggregated BNG architecture is important to the BBF. RTGWG intends to evaluate these proposals. RTGWG may adopt one, both, or neither of these proposals as starting points for RTGWG to produce specifications with the intention of requesting publication by the IESG as RFCs. In that context, we look forward to coordinating with BBF as we progress this work. The second liaison from the BBF discusses collaboration between the WWC work area of the BBF and 3GPP to specify 5G Fixed Mobile Convergence. It also discusses future work by the BBF to study the feasibility of using a single protocol to allow multi-dimension inter-operability and satisfy the requirements of both TR-384 and BBF FMC work. We would appreciate any additional information that the BBF can communicate regarding these initiatives to provide additional architectural context to guide IETF work in this area. We would like to pursue a plan consistent with the intent of the BBF expressed in the liaison statements referenced above. We welcome feedback and further dialog as the work of both organizations on this topic progresses. |
