Hi, DMM experts:
Good day. As my co-author Zhiwei has made the DMM WG aware in the following email, the authors of the MCN draft have recently submitted a newer version (ver#14) ‘Mobility Capability Negotiation’, and are currently planning to present in-person in the coming IETF-121 meeting. As you may know, this work has been presented a couple of times over the past year in different IETF meetings (116, 117, 119). Accordingly, we received a lot of valuable comments & suggestions from various types of channels (via IETF DMM sessions, email, f2f talks, etc.). Along the time, especially based on the feedback from the past couple of sessions, we have made significant editing of the document and then restructured the draft accordingly (as the 14th version now). In the newer version(s) of the draft, we started by talking about the common mobility capabilities including the supported and provisioned resources along with associated protocols for certain mobility management scenarios. Then, we generalized two protocol categories for mobility capability negotiation & management, i.e., the host-initiated category that involves the direct & active engagement of mobile end devices vs. the network-based category over which mobile endpoints play almost no role in the process, for both domains. After that, we applied the categorization to analyze the mobility capability negotiation for both the mobile IPv6 and the 3GPP 5G system. We also further dived into the 5G roaming cases, the Home-Routed (HR) and the Local BreakOut (LBO) roaming, which indeed reflect the feasibility of our protocol dichotomy. Also, the progressive relations among different chapters are better reflected. As Zhiwei has pointed out below, this draft revolves around the management plane of both mobile-IP and mobile wireless (specifically in 5G domain). When we look at the recent documents of the DMM WG, we have to acknowledge that almost all of them are focusing on the data-plane of the mobile wireless. So, we believe this draft (on Mgmt. plane) shall be good complement to DMM’s work. In summary, DMM experts, we appreciate if you can spare some time to read the draft and then share your comments. Thank you for your time! BR, -Tianji From: "Z.W.

Any comments are welcome.

Name: draft-yan-dmm-man Revision: 14 Title: Mobility Capability Negotiation Date: 2024-09-19 Group: Individual Submission Pages: 17 URL: https://www.ietf.org/archive/id/draft-yan-dmm-man-14.txt Status: https://datatracker.ietf.org/doc/draft-yan-dmm-man/ HTMLized: https://datatracker.ietf.org/doc/html/draft-yan-dmm-man Diff: https://author-tools.ietf.org/iddiff?url2=draft-yan-dmm-man-14 Abstract: Mobile peers exchange signals with networks, for both wireline and wireless domains, to negotiate capabilities for mobile registration, connection management, session establishment, service provisioning, etc. Generally, mobility capabilities include the supported and provisioned resources along with associated protocols for certain mobility management scenarios. While devices in the mobile wireline (IP) domain would mostly focus on the IP-related negotiation, devices in the wireless domain, e.g., the 5G system (5GS), embrace both mobile IP-related resources as well as wireless-specific capabilities. Regarding both the mobile-IP and wireless domains, we have generalized two protocol categories for mobility capability negotiation & management, i.e., the host-initiated category that involves the direct & active engagement of mobile end devices vs. the network-based category over which mobile endpoints play almost no role in the process. The classification and then the application of the two categories help us analyze the mobility capability negotiation for both the mobile IPv6 and the 3GPP 5G system. The comparison of the capability negotiation under both the Home-Routed (HR) and the Local BreakOut (LBO) roaming cases in 5GS further reflects the feasibility of the protocol dichotomy.
