HI Kalyani, Yes, a call to better understand the requirement will be great. I asked for some clarifications from CT4 Chair and copied dmm@ietf.org<mailto:dmm@ietf.org>. But didn't get a reply so far. So, a call would definitely help.
I am on Canada East Coast. 10am East Coast usually works for Europe, but might not work for folks in China, Japan, or people on the West Coast. If people have presentations, I can arrange a WebEx meeting as well. Either way, a call will be very helpful.

It seems like folks would like to understand more before they can provide feedback and comments. I can host a call on Monday, January 29th. Can you suggest a time that would work for most time zones? I am located on US East Coast.

I think Kalyani's work is extremely valuable, but we also need to set an strategy for our reply back to 3GPP. Currently most discussions are about individual protocols such as SRV6, LISP/ILSP, ILNP, ILA, etc. which are really in one form or another a type of ID-Location approach. I believe we first need to address 3GPP's request from the architecture point of view, before we dive into implementation details. Is there any discussion around different competing network architectures? Not sure if you have seen a white paper titled "Evolving 5G Routing" by Docomo, Huawei and others. We also hosted a live webcast demo that shows two LTE slices using ID-Location for data path and distribute ID-Location information to interested eNodeBs via public cloud pub/sub service. The result is very promising and shows the capability of this architecture. I believe the combination of the white paper and the demo could perhaps serve as a good starting point to get the architecture discussion going and that's where conference calls can come handy. I agree though let's start with the mailing list and move to calls next.

I guess, what you are asking for is a WG-chair scheduled conference calls? DMM List may be very quite, but there have been regular conf calls between authors of some of the WG documents. Authors of FPC host those calls regularly. For the new work item that Kalyani is proposing, we need to have some discussions in the mailer and once the document is adopted as a WG document, we can certainly host some calls (author/chair scheduled) on a need basis. So, the first step is to post comments on the documents and trigger some discussions.

I have extracted some diagrams from 3GPP specs and will redo them in ASCII after I get some feedback on whether to include them or not in this document.

Attached is an outline. Please let me know if you would like to contribute. Kalyani Bogineni Verizon
