           Logical Interface Support for multi-mode IP Hosts
             draft-ietf-netext-logical-interface-support-10

Abstract

   A Logical Interface is a software semantic internal to the host
   operating system.  This semantic is available in all popular
   operating systems and is used in various protocol implementations.
   The Logical Interface support is required on the mobile node
   operating in a Proxy Mobile IPv6 domain, for leveraging various
   network-based mobility management features such as inter-technology
   handoffs, multihoming and flow mobility support.  This document
   explains the operational details of Logical Interface construct and
   the specifics on how the link-layer implementations hide the physical
   interfaces from the IP stack and from the network nodes on the
   attached access networks.  Furthermore, this document identifies the
   applicability of this approach to various link-layer technologies and
   analyzes the issues around it when used in context with various
   mobility management features.
