Abstract

   The Locator/Identifier Separation Protocol (LISP) aims at improving
   the Internet routing scalability properties by leveraging on three
   principles: address role separation, encapsulation, and mapping.  In
   this document, based on implementation work, deployment experiences,
   and theoretical studies, we discuss the impact that the deployment of
   LISP can have on both the routing infrastructure and the end-user.

1.  Introduction

   The Locator/Identifier Separation Protocol (LISP) relies on three
   principles to improve the scalability properties of Internet routing:
   address role separation, encapsulation, and mapping.  The main goal
   of LISP is to make the routing infrastructure more scalable by
   reducing the number of prefixes announced in the Default Free Zone
   (DFZ).  As LISP utilizes mapping and encapsulation technologies, it
   provides additional benefits beyond routing scalability.  For
   example, LISP provides a mean for a LISP site to precisely control
   its inter-domain outgoing and incoming traffic, with the possibility
   to apply different policies to different domains exchanging traffic
   with it.  LISP can also be used to ease the transition from IPv4 to
   IPv6 as it allows the transport of IPv4 over IPv6 or IPv6 over IPv4.
