      Logical-interface Support for Multi-access enabled IP Hosts
             draft-ietf-netext-logical-interface-support-11

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 attached
   to 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 conjunction with various mobility
   management features.
