From: dmm [mailto:dmm-boun...@ietf.org] On Behalf Of Lyle Bertz Sent: Tuesday, March 20, 2018 6:57 AM To: dmm <dmm@ietf.org> Subject: [E] Re: [DMM] draft-bogineni-dmm-optimized-mobile-user-plane-00 We'll be quite time constrained during this session so I thought I would ask a couple of simple questions which I hope have already been addressed in previous e-mails: 1. Figures 14 & 15 are described as options and do not include an SMF. However, Figures 16 & 17 do. It is a bit confusing. Are 14 & 15 incorrect or is an option to skip the SMF? If correct, how does one do any policy in those figures? [KB] Slide #12 in the presentation show the complete diagrams, the document needs to be updated. https://datatracker.ietf.org/meeting/101/materials/slides-101-dmm-optimized-mobile-user-plane-solutions-for-5g-00 2. ILA appears to be super NAT'g (more than 1 NAT) but it is unclear how policy works. I am not sure that in its current state the proposed ILA design addresses in Section 3. Although it is noted that not all functions are supported at a specific UPF it is unclear that policy, lawful intercept, etc.. is supported at all. Will this be section be updated? [KB] the sections will be updated to show how each solution meets the requirements in Section 3. 3. Will a feature support comparison be made for each solution with the UPF functions to ensure coverage? [KB] That is the plan. 4. Will MFA be proposed as an option draft-gundavelli-dmm-mfa-00 [KB] I will let Sri answer this. )? Thanks! Lyle
