Internet-Draft   The IPv6 Hop-by-Hop Option for Geocast    December 2016

Abstract

   For IPv6-based ITS applications, ITS data packets are required to
   be delivered to a specific destination area, which is called geocast.
   In this draft, a new IPv6 Hop-by-Hop option, the IPv6 Geocast
   Hop-by-Hop option, with the geographical information of the
   destination area and the forwarding mechanism information is defined.

   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 [RFC2119].

   
2.  Introduction

   For the support of IPv6-based ITS (Intelligent Transportation System)
   applications, ITS data packets are required to be delivered based
   on the geographical location (longitude and latitude) information of
   the destination ITS node or area. The latter is called geocast
   [Geocast].

   From the considerations in [Geo-Problem], in this draft, we define
   the new IPv6 Geocast Hop-by-Hop option with the geo-location
   information of the center point and the radius information of
   the destination area. Also, the IPv6 Geocast Hop-by-Hop option
   has the fields for the geographical unicast mechanism
   from the originator to the center point of the destination area and
   the geographical broadcast mechanism from the center point to
   all the ITS nodes in the destination area.

3. Terminology

   ITS node
      A vehicle or a device that may generate ITS-related data
      in the form of IPv6 datagrams

   Geo-location
      The location of an ITS node represented in the form of
      longitude and latitude. The geo-location information
      is represented in the form of the World Geodetic System 1984
      (WGS84) [WGS-84] formatted coordinates.

   Geographical Forwarding
      IPv6 datagram forwarding based on the geo-location information
      of the source and the destination ITS node or area.
      Geographical unicast/broadcast and geocast belong to geographical
