     A Framework of Media-Independent Pre-Authentication (MPA) for
                   Inter-Domain Handover Optimization

Abstract

   This document describes Media-independent Pre-Authentication (MPA), a
   new handover optimization mechanism that addresses the issues on
   existing mobility management protocols and mobility optimization
   mechanisms to support inter-domain handover.  MPA is a mobile-
   assisted, secure handover optimization scheme that works over any
   link layer and with any mobility management protocol, and is most
   applicable to supporting optimization during inter-domain handover.
   MPA's pre-authentication, pre-configuration, and proactive handover
   techniques allow many of the handoff-related operations to take place
   before the mobile node has moved to the new network.  We describe the
   details of all the associated techniques and their applicability for
   different scenarios involving various mobility protocols during
   inter-domain handover.  We have implemented the MPA mechanism for
   various network-layer and application-layer mobility protocols, and
   we report a summary of experimental performance results in this
   document.

   This document is a product of the IP Mobility Optimizations (MOBOPTS)
   Research Group.
