Abstract

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

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".
