          [14:30] Introduction and draft status (Bhandari/Gomez)
          
              Note Well is presented.
          
              Agenda: no comment.
          
              Drafts status
                  IPv6 over NFC: Erik. IESG concerned that NFC specification
                  not publicly available. Erik got access. Way to proceed being
                  discussed.
                  IPv6 over PLC: authors responded to most comments
          
          [14:35] IPv6 ND Multicast Address Listener Registration (Pascal Thubert)
          
              a family of RFCs/drafts revolving around ND, more specifically
              Stateful Address Autoconfiguration.
              this draft includes ND and RPL stuff in one document, unlike the
              RFC8505+9010 pair.
              6LBR now accepts multiple registrations for same address (multicast).
              this spec answers an explicit requirement by Wi-SUN.
              this includes brown field deployment over networks running MOP 1 or
              3.
              routing could be any protocol, not just RPL. Could use MPL as well.
              solicit reviews, would like to have a fst turn around time
              Carles: volunteers to review?
              Pascal: implementations would be very welcome as well.
              Swetha: what about other WGs?
              Pascal: will present at ROLL as well.
              Erik: PIM would be interested too.
          
          [14:55] IPv6 ND Unicast Lookup (Pascal Thubert)
          
              address maping now know by 6LBR, could respond to unicast address
              lookup, as opposed to multicast
              originally published in 2019, while LBR draft was completed. Didn’t
              find a home at 6MAN
              coming back to 6lo to complete work.
          
          [15:03] Transmission of SCHC-compressed Packets over IEEE 802.15.4
          (Carles Gomez)
          
              SCHC compression allows to achieve better compression than 6282 in
              some cases.
              interest in using SCHC compression on top of 6LoWPAN networks.
              a 1-byte Dispatch proposed, 1-byte RuleID.
              in SCHC as specified in RFC8724, it is assumed that “uplink” and
              “downlink” are implicitely known, not so in 6lo mesh networks.
              proposed to introduce “tx” and “rx” notions in 6lo-SCHC
              Dominique: what is the rationale for deciding on RuleID fixed length,
              and specifically 1 byte?
              Carles: 1 byte seemed enough for use cases in mind. Will reconsider
              choice of fixed length, tough.
              Pascal: LPWAN architecture has asymmetrical and symmetrical
              cases. Does this document fit in?
              Pascal: discovering dev-to-dev from address seems odd. In 15.4 we
              don’twhich node is the router.
          
          [15:14] Native Short Address for LLN Expansion (Luigi Iannone)
          
              changed title to better reflect application scope.
              Allocation Function is now open to upgrades.
              overall improvment of document
              authors consider it ready for WG adoption
              Carles: last meeting, concerns about renumbering on topology
              changes. Seeking discussion on the ML, see if the concerns hqve been
              adrressed.
              (in the chat) Erik Kline: the adoption discussion might want to
              include whether this is in scope of the existing 6LO charter
              (in the chat) Carles Gomez: Agreed. There is some routing
              functionality in the document as well.
              (in the chat) Luigi: The routing part is not the main part is just
              to cope with temporary changes. But happy to discuss more
              Pascal: yes, with 8-port switches; it zill work. Wires prevent from
              creating new links.
              Luigi: we provided a solution to renumbering, looking for comments
              if this is enough.
          
          [15:25] Short Hierarchical IP Addresses at Edge Networks (Haoyu Song)
          
              Communication between IoT devices within network is like edge
              network. Devices don’t need to know their prefixes.
              Variable-length addresses proposed, hierarchical scheme.
              looking for collaboration, find best home for this work
              Carles: please compare with 6282 and SCHC header compression
              Haoyu: one slide about this, will als provide more info.
              Carles: please advise if you can achieve smaller headers.
              Haoyu: this is without context, and only address.
              (in the chat) Eduard V: Dual homing to different Carriers would
              prevent the possibility for the variable destination addresses. Hence,
              DA would probably stay fixed. Source address could grow on every
              router upstream.
          
          [15:35] meeting is adjourned
          
          Meeting chat:
          
          Carles Gomez
          +1 on implementation feedback! ()
          20:24:32
          Erik Kline
          the adoption discussion might want to include whether this is in scope
          of the existing 6LO charter
          20:52:37
          Carles Gomez
          Agreed. There is some routing functionality in the document as well.
          20:53:24
          Luigi Iannone
          The routing part is not the main part is just to cope with temporary
          changes. But happy to discuss more

          21:00:43
          Source address could grow on every router upstream.
