Problem Statement for the use of IP in some ITS scenarios
draft-petrescu-its-problem-00

default router.  This mode of operation is not considered in this
      document.

   The peer-to-peer operation of a V2V topology is an important part in
   ITS applications such as C-ACC and Platooning.  This operation mode
   allows each vehicle to send and receive application data
   (coordinates, speed) as IP packets, without the need of assistance
   from fixed infrastructure.  Each vehicle is pre-equipped with a
   unique IPv6 prefix and each computer in a vehicle is identified by a
   unique IPv6 address.

   In order for one computer in one vehicle to reach another computer in
   another vehicle it is necessary that the embedded routers in each
   vehicle learn the IPv6 prefix (and/or the IPv6 address) of the other
   vehicles.  A prefix-exchange mechanism is needed, otherwise the IP
   communication can not be established.

   After each vehicle has informed the other vehicles nearby about its
   prefix, the forwarding tables of each vehicle must be updated to
   contain the tuple [prefix; IP address] of each other vehicles.  The
   updating must deal with situations when vehicles leave the network,
   otherwise numerous ICMP Destination Unreachable messages may occur on
   the inter-vehicle media.

   The problem is thus how to realize this prefix exchange.
