Abstract

   The Locator/Identifier Separation Protocol (LISP) aims at improving
   the Internet scalability properties leveraging on three simple
   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 Internet in general and the end-user in
   particular.

1.  Introduction

   The Locator/Identifier Separation Protocol (LISP) relies on three
   simple principles to improve the scalability properties of the
   Internet: address role separation, encapsulation, and mapping.  The
   main goal of LISP is to make the Internet more scalable by reducing
   the number of prefixes announced in the Default Free Zone (DFZ).  As
   LISP relies on mapping and encapsulation, it turns out that it
   provides more benefits than just increased scalability.  For
   instance, 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 to transport IPv4 over IPv6 or IPv6 over IPv4.
   Furthermore, LISP also provides a solution to perform inter-domain
   multicast.

   This document discusses the impact of LISP's deployment on the
   Internet and on end-users and shows the consequences of the
