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 

community.



This document is a product of the Mobility for IPv4

Working Group of the IETF.
