         Flow Bindings Initiated by Home Agents for Mobile IPv6

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 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.  Flow
   bindings initiated by a home agent are supported for mobile nodes
   enabled by both IPv4 and IPv6.
