Title : An Introduction to the LISP Location-Identity
Separation System

Abstract:
LISP is an upgrade to the architecture of the IPvN internetworking
system, one which separates location and identity (currently
intermingled in IPvN addresses). This is a change which has been
identified by the IRTF as a critically necessary evolutionary
architectural step for the Internet. In LISP, nodes have both a
'locator' (a name which says _where_ in the network's connectivity
structure the node is) and an 'identifier' (a name which serves only
to provide a persistent handle for the node). A node may have more
than one locator, or its locator may change over time (e.g. if the
node is mobile), but it keeps the same identifier.
One of the chief novelties of LISP, compared to other proposals for
the separation of location and identity, is its approach to deploying
this upgrade. (In general, it is comparatively easy to conceive of
new network designs, but much harder to devise approaches which will
actually get deployed throughout the global network.) LISP aims to
achieve the near-ubiquitous deployment necessary for maximum
exploitation of an architectural upgrade by i) minimizing the amount
of change needed (existing hosts and routers can operate unmodified);
and ii) by providing significant benefits to early adopters.
This document is an introduction to the entire LISP system, for those
who are unfamiliar with it. It is intended to be both easy to
follow, and also give a fairly detailed understanding of the entire
system.
