Mobile IPv4 describes how a Mobile Node can perform IPv4-layer
handoffs between subnets served by different Foreign Agents.  In
certain cases, the latency involved in these handoffs can be above
the threshold required for the support of delay-sensitive or real-time
services.  The aim of this document is to present two methods to
achieve low-latency Mobile IPv4 handoffs.  In addition, a combination
of these two methods is described.  The described techniques allow
greater support for real-time services on a Mobile IPv4 network by
minimizing the period of time when a Mobile Node is unable to send or
receive IPv4 packets due to the delay in the Mobile IPv4 Registration
process.  This memo defines an Experimental Protocol for the Internet
