                      LISP for the Mobile Network
                 draft-farinacci-lisp-mobile-network-02

Abstract

   This specification describes how the LISP architecture and protocols
   can be used in a LTE/5G mobile network to support session survivable
   EID mobility.  A recommendation is provided to SDOs on how to
   integrate LISP into the mobile network.

1.  Introduction

   The LISP architecture and protocols [RFC6830] introduces two new
   numbering spaces, Endpoint Identifiers (EIDs) and Routing Locators
   (RLOCs) which provide an architecture to build overlays on top of the
   underlying Internet.  Mapping EIDs to RLOC-sets is accomplished with
   a Mapping Database System.  By using a level of indirection for
   routing and addressing, separating an address identifier from its
   location can allow flexible and scalable mobility.  By assigning EIDs
   to mobile devices and RLOCs to the network nodes that support such
   mobile devices, LISP can provide seamless mobility.

   For a reading audience unfamiliar with LISP, a brief tutorial level
   document is available at [I-D.ietf-lisp-introduction].
