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.
