A hand-off is the process during which a node is handed off between
two mobility agents. Mobile IP hand-offs occur as a consequence of
lower layer (i. e., link-layer) hand-offs that signify a location
switch between two IP networks. For the duration of a Mobile IP
hand-off, a mobile node is unable to send or receive traffic. The
length of this disruption is considered critical because it can
affect the performance of communications. An additional factor that
is closely bound with that of Mobile IP hand-offs is that of agent
selection. That involves the selection of the most suitable mobility
agent from which a mobile node should receive service.
With the help of link-layer information such as signal strength, signal quality and throughput it is possible to accelerate Mobile IP
hand-offs on one side and on the other to lead to the selection of
the best possible mobility agent. This draft describes a policy
based Mobile IP handoff decision method (POLIMAND) that allows for
enhanced Mobile IP handoffs and optimal agent selection based on
link layer information.

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
