Proxy Mobile IPv6 (PMIPv6) [RFC5213] provides IP mobility to a mobile node that does not support Mobile IPv6 (MIPv6) [RFC3775] mobile node functionality. A proxy agent in the network performs the mobility management signaling on behalf of the mobile node. This model transparently provides mobility for nodes within a PMIPv6 domain. Nevertheless, the basic performance of PMIPv6 in terms of handover latency and packet loss is considered no different from that of Mobile IPv6.

                   Fast Handovers for Proxy Mobile IPv6


   Mobile IPv6 (MIPv6; RFC 3775) provides a mobile node with IP mobility    when it performs a handover from one access router to another, and    fast handovers for Mobile IPv6 (FMIPv6) are specified to enhance the    handover performance in terms of latency and packet loss.  While    MIPv6 (and FMIPv6 as well) requires the participation of the mobile    node in the mobility-related signaling, Proxy Mobile IPv6 (PMIPv6;    RFC 5213) provides IP mobility to nodes that either have or do not    have MIPv6 functionality without such involvement.  Nevertheless, the    basic performance of PMIPv6 in terms of handover latency and packet    loss is considered no different from that of MIPv6.

   When the fast handover is considered in such an environment, several    modifications are needed to FMIPv6 to adapt to the network-based    mobility management.  This document specifies the usage of fast    handovers for Mobile IPv6 (FMIPv6; RFC 5568) when Proxy Mobile IPv6    is used as the mobility management protocol.  Necessary extensions    are specified for FMIPv6 to support the scenario when the mobile node    does not have IP mobility functionality and hence is not involved    with either MIPv6 or FMIPv6 operations.
