Title : Fast Handover for Hierarchical MIPv6 (F-HMIPv6)

This document addresses Fast Handover over HMIPv6 networks. The MIPv6
mobility could be more enhanced by combining FMIPv6 with HMIPv6, in
which MIPv6 is benefited from all the advantages of the respective
schemes. An additional benefit by combining FMIPv6 with HMIPv6 is that
the overall handover latency in FMIPv6 will be more reduced since in
HMIPv6 the MN sends a location update with the local MAP, rather than
the HA and CN that are typically further way. This document describes
how to use FMIPv6 for HMIPv6 (F-HMIPv6). The F-HMIPv6 is designed to
be friendly with the data transport feature of HMIPv6. In F-HMIPv6,
the tunnel for fast handover is established between MAP and NAR,
rather than between PAR and NAR. For this purpose, the MN exchanges
the FMIPv6 messages with MAP, not PAR. The F-HMIPv6 utilizes the
FMIPv6 messages for handover support without further defining any new
messages. Two variants of F-HMIPv6 are also described: F-HMIPv6 with
bicasting and Reactive F-HMIPv6 without handover anticipation.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
