               An Architectural Introduction to the LISP
                  Location-Identity Separation System
                    draft-ietf-lisp-introduction-03

Abstract

   LISP is an upgrade to the architecture of the IP internetworking
   system, one which separates location and identity properties
   (previously intermingled in IP addresses).  This document is an
   introductory overview of the entire LISP system, and focuses on
   describing the major concepts and functional sub-systems of LISP, and
   the interactions between them.
