Transmission of IPv6 Packets over IEEE 802.11 Networks operating in mode
    Outside the Context of a Basic Service Set (IPv6-over-80211-OCB)
              draft-ietf-ipwave-ipv6-over-80211ocb-08.txt

Abstract

   In order to transmit IPv6 packets on IEEE 802.11 networks running
   outside the context of a basic service set (OCB, earlier "802.11p")
   there is a need to define a few parameters such as the supported
   Maximum Transmission Unit size on the 802.11-OCB link, the header
   format preceding the IPv6 header, the Type value within it, and
   others.  This document describes these parameters for IPv6 and IEEE
   802.11-OCB networks; it portrays the layering of IPv6 on 802.11-OCB
   similarly to other known 802.11 and Ethernet layers - by using an
   Ethernet Adaptation Layer.

   In addition, the document lists what is different in 802.11-OCB
   (802.11p) links compared to more 'traditional' 802.11a/b/g/n links,
   where IPv6 protocols operate without issues.  Most notably, the
   operation outside the context of a BSS (OCB) impacts IPv6 handover
   behaviour and IPv6 security.
