Flow Bindings in Mobile IPv6 and Network Mobility (NEMO) Basic Support
Abstract
This document introduces extensions to Mobile IPv6 that allow nodes
to bind one or more flows to a care-of address. These extensions
allow multihomed nodes to instruct home agents and other Mobile IPv6
entities to direct inbound flows to specific addresses.
