LISP-HNM: Integrated fast host and network mobility control in LISP networks

Abstract

At present, the well-known LISP-MN protocol for LISP mobility can only support end-host IP mobility, and need to implement lightweight version of LISP's ITR/ETR functionality on mobile nodes. Because of this, the LISP-MN protocol is hard for deployment, and lack of the support for network mobility. In this paper, we present LISP-HNM, a network-based end-host and network mobility support protocol in LISP networks. With LISP-HNM, end-hosts and networks mobility are controlled through the same access register protocol, while the core network provides the fast mobility support with a extensional mapping push operation. All end-hosts and hosts in mobile networks are assigning unchangeable IP addresses regardless of their network attachment points. This paper describes the protocol and presents a modelling performance comparison between LISP-HNM and LISP-MN.
