Technical Summary Mobile IPv4 describes how a Mobile Node can perform IP-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 IP 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 minimising the period of time when a Mobile Node is unable to send or receive IP packets due to the delay in the Mobile IP Registration process.
