   • What is IPWAVE Working Group
   • Main WG item: IPv6 over 802.11 OCB
   • Additional WG item: Problem Statement and Use Cases
   • Perspectives
     IPWAVE Working Group
     • IP Wireless Access in Vehicular Environments (IPWAVE) is a Working 
      Group at the Internet Engineering Task Force (IETF).
     • Works on “V2V and V2I use-cases where IP is well-suited as a 
      networking technology”.
     • Liaisons with ISO TC 204, SAE, ETSI ITS, IEEE, ITU CITS, ITU-R WP 5A.
     • Group formed in year 2016, after successful Birds-of-a-Feather (BoF)

     • Email list, roughly 340 subscribers

               Main Work Item: IPv6 over 802.11-
               OCB
               •   draft-ietf-ipwave-ipv6-over-80211ocb-52  publicly accessible
               •   IEEE 802.11p is a MAC and PHY layer for vehicular wireless networks:
                       •  Operates Outside the Context of a BSSID (802.11-OCB).
                       •  Works at 5.9GHz bands channels with a short 10MHz width.
                       •  Requires the use of 802.11 “QoS Data” headers.
                       •  Higher power levels are allowed (33 dBm, 40 dBm, country-specific).
                       •  Future evolutions: 802.11bd.
               •   Running an IP layer on 802.11-OCB requires the definition of a few parameters:
                       •  EtherType is 0x86DD
                       •  Default MTU is 1500 bytes, minimum MTU size is 1280 bytes
                       •  Priority (TID) is 1, i.e. ‘Background’, also known as ‘AC_BK’
                       •  Interface Identifiers are: 
                              •   based on EUI-64, or are ‘Stable’ or ‘Opaque’ IIDs;
                              •   of length 64 bit.
               •   Use IPv6-over-Ethernet [RFC2464], and a simple “frame translation from 802.3 to 802.11 in order to minimize the code  
                   changes.”
               •   Subnet structure: recommendations on the use of Neighbor Discovery and Mobile IPv6 protocols in vehicular settings.
               •   Security considerations, privacy.
      Status
      • RFC 8691 “Basic Support for IPv6 Networks Operating Outside the Context of a Basic 
       Service Set over IEEE Std 802.11”
        • issued in December 2019
      • Implementation of RFC 8691 is straightforward:
        • Available as a patch to linux kernels (some parts fully integrated in mainline)
          See an OCB patch for 16mbit/s and less, at e.g. https://github.com/jfpastrana/ath9k_ocb_linux_4.2.8
        • Not yet available on BSD systems
        • Advancements towards the use of IPv6 with ath10k drivers
          • For a higher bandwidth OCB (more than 16mbit/s for vehicle networks, e.g. 1Gbit/s)
            • See the OCB patch at:
              https://gitlab.com/hpi-potsdam/osm/g5-on-linux/11p-on-linux/-/tree/ath10k
              (important note: contrary to github, one can browse that gitlab URL on IPv6 as well, without a need of having IPv4 on the 
              computer)
            Topologies for using IPv6 for Vehicle 
            Networks
