Multicast Mobility Routing Optimizations for Proxy Mobile IPv6
Abstract
This document proposes some experimental enhancements to the base
solution to support IP multicasting in a Proxy Mobile IPv6 (PMIPv6)
domain. These enhancements include the use of a multicast tree
mobility anchor as the topological anchor point for multicast
traffic, as well as a direct routing option where the Mobile Access
Gateway can provide access to multicast content in the local network.
The goal of these enhancements is to provide benefits such as
reducing multicast traffic replication and supporting different
PMIPv6 deployment scenarios.
