** IPWAVE WG documents

17:50 Transmission of IPv6 Packets over IEEE 802.11 Networks in mode 
      Outside the Context of a Basic Service Set (IPv6-over-80211ocb) 20 min
      Presenter: Alex Petrescu
      Draft: draft-ietf-ipwave-ipv6-over-80211ocb-11

AP presented the draft. There are some uresolved issues like:

  - Request or not request the group ID from IANA?
  - Is the use of ND adapted for OCB or not adopted?

    * Sri Gundavelli (SG): group ID is not needed; it has been discussed at the
      ML
    * SG: why ND is needed? 
    * AP: it is an open issue to be discussed.

  - AP presents the overview of changes since the draft version 05. He asks
    reviewers to look and check at the change log of the draft. He presents the
    addressed technical changed by each one.

    * SG recommends not touch about QoS data. He asks the meaning of QoS data in
      the draft.
    * AP explains the definition of QoS data in the context of 802.11 OCB. There
      is no mention of the specific QoS parameters. 
    * CB clarifies that it is about the use of 802.11 QoS Data Headers.

  - AP presents the changes about authorship, references, terminology, some
    moved sections to Appendix, readability, security. AP says that the draft
    addressed all comments received from the 7 reviewers.

    * Charlie Perkins (CP) comments that not defining OBU makes it hard to read.
    * AP answers that IETF cannot define OBU (On-Board Unit) because it is
      defined elsewhere. In addition, it is different from the definition of OBRU
      (On-Board Router Unit) defined here in IETF.

    * Erik says that the MAC address generation in Appendix F.4 is something to
      be corrected in the draft.  
    * AP agrees with Erik.
    * CB comments that only 46 bits can be changed when the local bit is set.
      There is work on IEEE 802 about privacy that needs to be checked.
    * Suresh Krishnan (SK) sais that he will check.

    * Michelle Wetterwald (MW) asks if dropping the group multicast ID is final.
    * CB confirms it is for this document, but nothing prevents this to be
      revisited in the future in a different document.

  - SK comments that the draft does not read like a standard. It needs some
    changes such as to how the document is written, not on the content. Please check
    with Carlos.

18:10 IP-based Vehicular Networking: Use Cases, Survey
      and Problem Statement ......................................... 20 min
      Presenter: Yiwen (Chris) Shen 
      Draft: draft-ietf-ipwave-vehicular-networking-00

  - Yiwen Shen (YS) presents the draft.
  - CB asks people to review the draft. Since rechartering discussion is
    expected to take place once the first WG deliverable is sent to IESG, it is
    important that this document captures those problems that the WG finds
    interesting.
