The Mobile IP protocol allows a Mobile Node to continue using the
same home address even after changing its point of attachment to the
Internet.  This provides transparency to most existing applications
that assume a fixed address and a fixed point of attachment.
However, new applications, such as voice-over-IP, have additional
real-time requirements such that a change in the point of attachment
will cause a noticeable degradation of service unless additional
steps are taken to reduce the latency of a handoff event.
This specification proposes extensions to the Mobile IP protocol that
may be used by Foreign Agents to set up a Mobile Node's visitor
entry, and forward its packets, prior to receiving a formal
Registration Request from the Mobile Node.  This enables a very rapid
establishment of service at the new point of attachment so that the
effect of the handoff on real-time applications is minimized.

In the body type:

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.
