A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Mobility for IP: Performance, Signaling and Handoff Optimization Working Group of the IETF.


	Title           : Fast Handovers for Proxy Mobile IPv6
	Author(s)       : H. Yokota, et al.

Mobile IPv6 (MIPv6) [RFC3775] 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) [RFC5568] 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) [RFC5213] provides IP mobility to mobile 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 not any 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
Mobile IPv6 (FMIPv6) 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.
