Title : Adapting Mobile IPv6 Fast Handovers for IPv4
Author(s) : R. Koodli, C. Perkins
Filename : draft-koodli-fmipv4-00.txt
Pages : 20
Date : 2004-10-19
The Mobile IPv6 fast handover document [2] specifies a protocol to
improve latency and packet loss resulting from Mobile IPv6 handover
operations. This document adapts the protocol for IPv4 networks
to improve performance over Mobile IPv4 operations, including
processing of Agent Advertisements, new Care of Address acquisition
and Registration Request and Reply. However, Foreign Agent operation
at a router is not necessary. Also, the protocol may be used
transparently on hosts which do not support Mobile IP, but with
limited movement across subnets.
Using the concepts outlined in [2], this document also addresses
movement detection, IP address configuration and location update
latencies. For reducing the IP address configuration, the draft
provides two alternatives. First, the new CoA is always made to be
the new access router's IP address. Second, a hash algorithm is used
to produce a new CoA, and any conflicts are resolved so as not to
cause traffic misdirection.

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
Internet-Draft.
