       Multicast Listener Extensions for Mobile IPv6 (MIPv6) and
               Proxy Mobile IPv6 (PMIPv6) Fast Handovers

Abstract

   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".
