Distributed Mobility Anchoring Using LISP Mobile Node

Abstract

At the 2019 ICNS conference the paper "Distributed Mobility Anchoring in the ATN/IPS" [1] described how Mobile IPv6 (MIPv6) Home Agents could be deployed in a distributed fashion as regional mobility anchors, for example, in each ICAO region. In this environment a Mobile Node (MN) would register with the regional HA once it attached to the terrestrial access network in that region.After further investigation we have determined that the challenge with this approach is that COTS MIPv6 Home Agents do not support the required MIPv6 extensions even though there are "Standards Track" RFCs that define these extensions. Furthermore COTS Home Agents can only be configured as being topologically fixed in the routing infrastructure, that is, they are not distributed.This paper maintains the distributed mobility anchoring paper architecture described in our 2019 paper but instead of using MIPv6 it uses regional mobility anchors based on the Locator/ID Separation Protocol (LISP).
