                   Flow Binding Support for Mobile IP
             draft-ietf-mip4-multiple-tunnel-support-12.txt

Abstract

   This specification defines extensions to Mobile IP protocol for
   allowing a mobile node with multiple interfaces to register a care-of
   address for each of its network interfaces and to simultaneously
   establish multiple IP tunnels with its home agent.  This essentially
   allows the mobile node to utilize all the available network
   interfaces and build an higher aggregated logical pipe with its home
   agent for its home address traffic.  Furthermore, these extensions
   also allow the mobile node and the home agent to negotiate IP traffic
   flow policies for binding individual flows with the registered
   care-of addresses.
