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.
