Re: [Banana] Charter Text w/Milestones

Hi Mirja:

This in some ways will probably be an unsatisfactory answer, simply as some of this is work in progress. But I'll see what I can do.

CPE configuration is currently specified in the BBF based on TR-69 with the various data models for services in the home specified in TR-181 which has a lost list of amendments to extend it . We are expecting to carry this forward as part of our cooperation with 3GPP on "5G fixed access" including hybrid access, which will mean a data model for hybrid access is to be defined.  The consensus for the providers interested in Hybrid access is that the 3GPP Gx interface (Diameter based) would be used for at least the policy aspects of the HAG/network side proxy.  IIRC TR-69 today is bootstrapped via a DHCP option and then RPC like calls to a configuration server, and we expect to extend that into the 5G N1 interface procedures for network attachment.

I'm not 100% clear on what is considered to be in the scope of signaling in this discussion. The solutions the BBF has agreements to make normative (at least draft-zhang-gre-tunnel-bonding and mp-tcp) seem to be self contained from the point of view of peer exchanges between the proxies for flow control etc.   The value we are expecting to add is in the form of deployment scenarios, addressing, and policy models.

I hope this helps
Dave

Hi David,

one question:

As such, operators already have tools to do a chunk of this (e.g. policy and configuration) which they will simply extend as necessary vs. deploy new protocols.

Can you provide more information which tools/protocols are in use? I think one important comment for the charter is that also the signaling protocol can be an extension to an existing protocol or multiple existing protocols if bootstrapping and state control are done by different protocols, if suitable. Especially if those protocols are IETF protocols this is IETF work. But yes, cooperation with 3GPP as well as BBF seems important here. Usually we use our liaisons for this!
