        Transmission of IPv6 Packets over IEEE 802.11p Networks
                 draft-petrescu-ipv6-over-80211p-00.txt

Abstract

   In order to transmit IPv6 packets on IEEE 802.11p networks there is a
   need to define a few parameters such as the recommended Maximum
   Transmission Unit size, the header format preceding the IPv6 base
   header, the Type value within it, and others.  This document
   describes these parameters for IPv6 and IEEE 802.11p networks; it
   portrays the layering of IPv6 on 802.11p similarly to other known
   802.11 and Ethernet layers, by using an existing Ethernet Adaptation
   Layer.

   In addition, the document attempts to list what is different in
   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
   802.11p link is given.
