    Considerations for ID/Location Separation Protocols in IP-based
                           Vehicular Networks
                draft-kjsun-ipwave-id-loc-separation-01

Abstract

   ID/Location separation protocols are proposed for scalable routing,
   enhancing mobility and privacy in IP based internet infrastructure.
   When we consider IP based vehicular networks, ID/Location separation
   architecture is expected to offer benefits.  In this draft, we
   analyze whether ID/Location separation protocols can adjust into IP
   based vehicular networks and solve requirements.

1.  Introduction

   For vehicular networks, it is required to provide connection to the
   Intelligent Transport System (ITS) for the driver's safety, efficient
   driving and entertaining with fast mobility management.  Other
   scenarios besides V2I communication, like V2V and V2X communication
   are also considered.  Link layer protocols such as IEEE 802.11 OCB
   are already defined for low-latency and alternative networks, and it
   is designed for enabling IPv6 as a network layer protocol.
   Nevertheless, for using IPv6 in the vehicular network, there are some
   requirements for optimization as described in
   [ietf-ipwave-vehicular-networking].  These issues are classified into
   neighbor/service discovery, mobility management, security and
   privacy.

   In IETF, there are several ID/Location separation protocols such as
   LISP [RFC6830] and ILNP [RFC6740] for scalable routing, enhancing
   privacy and mobility management.  Currently ID/Location separation
   concept is useful not only for decomposing ID/Location from an IP
   address, but also for control/data plane separation which is a major
   evolution of the internet infrastructure.  For the vehicular network,
   ID/Location separation protocols can be expected to meet requirements
   and solve problem statements discussed in IPWAVE WG.  In this draft,
   we describe use cases for applying ID/Location separation
   architecture into IP-based vehicular network, and analyze whether
   such protocols can meet requirements for IPv6 in vehicular networks.
