LISP-MN: Mobile Networking Through LISP

Free registration required

Executive Summary

The current internet architecture was not designed to easily accommodate mobility, because IP addresses are used both to identify and locate hosts. The Locator/Identifier Separation Protocol (LISP) decouples them by considering two types of addresses: EIDs that identify hosts, and RLOCs that identify network attachment points and are used as routing locators. LISP, with such separation in place, can also offer native mobility. LISP-MN is a particular case of LISP which specifies mobility. In this paper, the authors provide a comprehensive tutorial on LISP-MN, showing its main features and how it compares to existing mobility protocols.
