Introduction In the IEEE 802.11p OCB mode, all nodes in the wireless range can directly communicate with each other without authentication/ association procedures, thus data exchange between nodes can be established in fractions of seconds. The IEEE 802.11p OCB mode has the following properties: o Wildcard BSSID (i.e., all bits are set to 1) used by each node o No beacons transmitted o No authentication required o No association needed o No encryption provided o dot11OCBActivated OID set to true This document describes the transmission of IPv6 packets over the IEEE 802.11p OCB mode. 2. Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. Lee & Petrescu Expires January 9, 2017 [Page 2] Internet-Draft IPv6-over-80211OCB July 2016 OCB - Outside the Context of a BSS. 802.11-OCB - IEEE 802.11-2012 text flagged by "dot11OCBActivated". This means: IEEE 802.11e for quality of service; 802.11j-2004 for half-clocked operations; and 802.11p for operation in the 5.9 GHz band and in mode OCB. 3. Maximum Transmission Unit The default MTU size for IPv6 packets on an 802.11-OCB link is 1500 octets. This size may be reduced by a Router Advertisement containing an MTU option which specifies a smaller MTU, or by manual (or DHCPv6) configuration of each node. If a Router Advertisement received on an 802.11-OCB interface has an MTU option specifying an MTU larger than 1500 octets, or larger than a manually configured value, that MTU option may be logged to system management but must be otherwise ignored. Non-IPv6 packets such as WAVE Short Message Protocol (WSMP) can be delivered on 802.11-OCB links. Specifications of these packets are out of scope and do not impose any limit on the MTU size, allowing an arbitrary number of 'containers'. 4. Frame Format IPv6 packets can be transmitted as "IEEE 802.11 Data" or alternatively as "IEEE 802.11 QoS Data".
