Chair presented IESG review comments/status

• Mobility-awareness & key technical contributions

Draft: UDP Tunnel extension YANG

• not much update
• presenter shows a YANG module (ietf-ac-udpt), saying no change
• The only changes are in IANA section

Draft: MUP architecture

• author went thru updates (ST2 route, MUP extended community:
  Interwor segment type, security consideration, etc.)
• Authors asked WG to review the draft and provide feedback.
• Tom Hill: comment on securty, need to reference RFC 8754, 8986
  for more details on SRv6 secuirty; should not define what
  inter-domain SRv6 security is in this draft

Draft: Mobile traffic steering

• Author went thru changes since WG adoption in dec. 2024
• Authors listed a few items requesting comments from the WG
  (items shown in slide deck)
• Chair putting out a poll on how many have read the draft.
  accorindg to the poll result, the chair suggested more to read
  the draft and then provide feedback.

Draft: Architecture Discussion on SRv6 MUP

• Author went thru changes (shown in slide deck), e.g., document
  positioning, uSID, etc.)
• John Kaippallimalil: Comments on session-based paradigm: both
  3GPP and here have session controllers, how to handle O(n^2)
  case.
• Tianji Jiang: comments on any-to-any communication: author
  clarified the draft targets at lowering down from O(N^2) to O(N)

Draft: Mobile User Plane Evolution: 5G & 6G

• Author presented ongoing discussion captured from the User Plane
  architecture in 6G Architecture study (TR 23.801)
• Jeffley Zhang: questioned the contradiction between 3GPP's
  transport-agnostic requirements and proposals to natively
  replace GTP-U with SRv6. Tingji noted that native SRv6
  replacement remains an active proposal under discussion.
• Weiqiang Cheng: Comments on the possibility of a partial GTP-U
  replacement to integrate edge computing, suggesting that IETF
  network experts should provide architectural proposals to 3GPP.

Draft: Requirements of SRv6 for the 6G User Plane

• authors present the neceessity to apply SRv6 to 6G UP
• John Kaippallimalil: Comments: consider the use case: roaming
  across multi-domain
• Chairs: collaborate with 6G-MUP-evolution draft
• Weiqiang Cheng: Comments: since we have discussed lots on how
  SRv6 might benefit 3GPP; So, should we start considering some
  sort of liaison to 3GPP regarding SRv6 applicablity? need more
  discussions.
