LISP Impact
draft-saucez-lisp-impact-03.txt
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, deployment, and theoretical
studies, we discuss the impact that deployment of LISP can have on
both the Internet in general and for the end-users in particular.

1. Introduction
The Locator/Identifier Separation Protocol (LISP) relies on three
simple principles to scale 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 well as its related churn. As LISP
relies on mapping and encapsulation, it turns out that it provides
more benefits than just 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 the 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.
