Mobile IPv6 [RFC6275] defines a network-layer mobility protocol involving participation by Mobile Nodes, while Proxy Mobile IPv6 [RFC5213] provides a mechanism without requiring mobility protocol operations at a Mobile Node (MN). Both protocols introduce traffic disruptions on handovers that may be intolerable in many real-time application scenarios such as gaming or conferencing. Mobile IPv6 Fast Handovers (FMIPv6) [RFC5568] and Fast Handovers for Proxy Mobile IPv6 (PFMIPv6) [RFC5949] improve the performance of handovers for unicast communication. Delays are reduced to the order of the maximum of the link switching delay and the signaling delay between Access Routers (ARs) or Mobile Access Gateways (MAGs) [FMIPv6-Analysis].

Multicast Listener Extensions for Mobile IPv6 (MIPv6) and Proxy Mobile IPv6 (PMIPv6) Fast Handovers
Fast handover protocols for Mobile IPv6 (MIPv6) and Proxy Mobile IPv6
(PMIPv6) define mobility management procedures that support unicast
communication at reduced handover latency. Fast handover base
operations do not affect multicast communication and, hence, do not
accelerate handover management for native multicast listeners. Many
multicast applications like IPTV or conferencing, though, comprise
delay-sensitive, real-time traffic and will benefit from fast
handover completion. This document specifies extension of the Mobile
IPv6 Fast Handovers (FMIPv6) and the Fast Handovers for Proxy Mobile
IPv6 (PFMIPv6) protocols to include multicast traffic management in
fast handover operations. This multicast support is provided first
at the control plane by management of rapid context transfer between
access routers and second at the data plane by optional fast traffic
forwarding that may include buffering. An FMIPv6 access router
indicates support for multicast using an updated Proxy Router
Advertisements message format.
This document updates RFC 5568, "Mobile IPv6 Fast Handovers".
