      Presenters: Russ Housley (RH) and Carlos Bernardos (CB)
------------------------------------------------------------------------

CB bashes the agenda. RH reports on a liaison from ITU-T SG16. CB reports on the
WG status update, with two active WG documents: one about transmission of IPv6
over IEEE802.11-OCB and one on problem statement and survey. The first document
received some comments from 6man and during the session it will be discussed if
changes remain to be done Regarding the PS document, at least 2 additional
reviews are needed before the document is progressed.

** IPWAVE WG documents

11:35 Transmission of IPv6 Packets over IEEE 802.11 Networks  ... 20 min
      in mode Outside the Context of a Basic Service Set
         Presenter: Nabil Benamar (NB)
         Draft: draft-ietf-ipwave-ipv6-over-80211ocb-30
------------------------------------------------------------------------

NB presents the slides, highlighting some modifications for comments from 6man.

Erik Nordmark (EN) comments that a sentence in te draft about reliability is not
correct and that unicast transmission is as bad as multicast in 802.11-OCB, as
there are no ACKs. 

CB comments that 6man comments should be solved. The current document is not
providing the solved issues. We need another revision of this document.

Suresh Krishan (SK), AD: The document needs changes; even if it takes time, we
need to do. Authors should go to 6man and address the issues to solve all of
them. SK asks if using an issue tracker could help, but it is decided to keep
using the mailing list.

EN: all the changes made to address 6man comments should be shown.

CB asks authors to send an e-mail summarizing how each of the 6man reviews have
been addressed. This needs to be clear to go back to 6man for a second review.

11:55  IP Wireless Access in Vehicular Environments (IPWAVE):  .. 20 min
       Problem Statement and Use Cases
          Presenter: Jaehoon Paul Jeong (PJ)
          Draft: draft-ietf-ipwave-vehicular-networking-07
------------------------------------------------------------------------

PK presents the vanet architecture with new link model, v2i, and v2v
communications. PJ explains that due to the new vehicular wireless link model,
the current ND protocol needed to be extended or improved.

CB ask for 2 volunteers to review the document. Sri Gundavelli and Charles
Perkins agree to do it.

Rahul Jadhav (RJ) comments on link layer and authentication.

Sri Gundavelli (SG): we do not make a specific solution in this document,
responding to RJ. It is a high level document.

Amelia Andersdotter (AA) points the human right review. PJ says that they can
discuss offline about that.

EN asks if there is any experience in handovers between RSUs, any implementation
test. PJ responds that no real experience done but experiments in the lab and
simulations.

------------------------------------------------------------------------
** Additional topics

12:15 IPv6 Neighbor Discovery for IP-Based Vehicular Networks  ... 5 min
          Presenter: Jaehoon Paul Jeong (PJ)
          Draft: draft-xiang-ipwave-vehicular-neighbor-discovery-00
------------------------------------------------------------------------

PJ presents the draft.

SG comments that the RSU seems to be a layer-2 node.
PJ replies that it is a layer-3 node.
SG says that it is not a layer-3 node, that discussion is needed

SK asks why there are two different documents (the one presented and another
one). PJ responds tha the documents are going to be merged.

CB comments that it would be good to have a hackathon on ipwave in the next
meeting. Nabil's team has been playing with implementation and PJ's teams is
also willing to participate and collaborate.
