Mobile IPv6 enables a mobile node to maintain its connectivity to the Internet when moving from one Access Router to another, a process referred to as handover. Handover involves link switching, which may not be exactly coordinated with fast handover signaling. The arrival pattern of packets is dependent on many factors, including application characteristics and network queuing behaviors. Hence, packets may arrive at the NAR before the MN is able to establish its link there. These packets will be lost unless they are buffered.
