Hi Xueyan,

Thank you for your support and for raisi= ng these two important topics.

The ANCP extensions for BNG CUPS and = the PPPoE over SRv6 work are excellent examples of what this list is meant = to address. The new mailing list is the right venue for both, especially wh= ere protocol extensions are involved. It will also help keep your planned A= NCP extensions for CUPS aligned with the ANCP LIHAWI draft I'm working = on.

I had completely missed the PPPoE over SRv6 draft, but I'm v= ery interested in it and will share my feedback on this list soon. It shows= exactly why broadband work needs a working group in the IETF.

Below= is my current list of active Internet-Drafts related to broadband access, = though I'm sure there are more:

Hi Christian and All,

Thank you for setti= ng up this mailing list and kicking off this discussion, and also thanks to= =C3=88ric Vyncke for his support.

As the BBF Liaison Manager, = I strongly agree that a dedicated space for broadband access-related work w= ithin the IETF is very necessary. As you pointed out, the protocols (e.g., = PPPoE, IPoE, ANCP) used in BBF but developed in BBF. This will bridge the g= ap, benefit and strenthen the collaboration between IETF and BBF. I fully s= upport pushing this work to an independent working group.

From my= perspective, there are already some topics that perfectly align with the s= cope of the list:
1. ANCP extensio= n for BNG CUPS: With the industry development of Contral and User Plane Sep= aration (CUPS) for BNG, the origional ANCP requires extensions. The extensi= ons may simplify CU configuration, optimize user plane management strategie= s, and improve the service activation rate for broadband suscribers. I plan= to submit a draft covering this work in October.
2. PPPoE over SRv6: We currently have a draft discussing SRv= 6 for PPPoE transport, which has been discussed in IETF 126 SPRING WG meeti= ng. While we received feedback suggesting this might be driven within BBF, = the core work involves protocol extensions, making this new Broadband list = a much more appropriate home for it.=C2=A0

I look forward to continuing= the dicussion on this topic here.

Best regards,
Xueyan
