           Home Agent Initiated Flow Binding for Mobile IPv6
               draft-yokota-mext-ha-init-flow-binding-02

Abstract

   There are scenarios in which the home agent needs to trigger flow
   binding operations towards the mobile node such as moving a flow from
   one access network to another based on the network resource
   availability.  In order for the home agent to be able to initiate
   interactions for flow bindings with the mobile node, this document
   defines new signaling messages and sub-options for Mobile IPv6.  Home
   agent initiated flow bindings are supported for both IPv4 and IPv6
   enabled mobile nodes.
