   Transmission of IPv6 Packets over IEEE 802.11 Networks Outside the
                     Context of a Basic Service Set

Abstract

   In order to transmit IPv6 packets on IEEE 802.11 networks run outside
   the context of a basic service set (OCB, earlier "802.11p") there is
   a need to define a few parameters such as the recommended Maximum
   Transmission Unit size, 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 attempts to list what is different in
   802.11 OCB (802.11p) compared to more 'traditional' 802.11a/b/g/n
   layers, layers over which IPv6 protocols run ok.  Most notably, the
   operation outside the context of a BSS (OCB) has impact on IPv6
   handover behaviour and on IPv6 security.

   An example of an IPv6 packet captured while transmitted over an IEEE
   802.11 OCB link (802.11p) is given.
