                   draft-li-ipv4-over-80211ocb-00.txt

Abstract

   This document describes the transmission of IPv4 packets over IEEE
   802.11-2012 networks when run Outside the Context of a BSS
   (802.11-OCB, earlier known as 802.11p).

1.  Introduction

   This document describes the transmission of IPv4 and ARP packets over
   IEEE 802.11-2012 networks when run Outside the Context of a BSS
   (802.11-OCB, earlier known as 802.11p), as documented in
   [IEEE802.11-2012].  IPv4 packets are encapsulated in a LLC SNAP layer
   and then the 802.11 MAC layer before transmission.

   In the following text we use the term "802.11-OCB" to refer to IEEE
   802.11-2012 when operated with the "OCBActivated" flag set.  Previous
   versions of other documents also referred to this as 802.11p.

   802.11-OCB networks are used frequently in vehicular communications
   and have specific safety related requirements that are not discussed
   here.  Nothing in this document should be construed to contradict,
   contravene, or otherwise deter compliance with other safety
   requirements and regulations.  Specifically, IPv4 is prohibited on
   the 802.11-OCB 'Control Channel' (channel 178 at FCC/IEEE, and 180 at
