摘　　要：移动IPv6允许用户在移动的过程中保持连续的通信,但是现有的各种基于移动IPv6的切换机制仍经受较大延迟,达不到对时延敏感的实时业务的要求。本文提出一种改进的层次型快速移动IPv6切换机制,通过在层次型移动IPv6上调整快速移动IPv6的信令流程,简化了切换预测阶段的操作,仿真表明该切换机制减少了整体切换延迟。Mobile IPv6 enables mobile users to communicate while moving. However, current handoff schemes still endure long delay, which can＇ t meet the demands for delay sensitive real - time applications. In this paper, an improved fast handoff scheme for hierachieal mobile IPv6 is offered. By adjusting signaling flow of FMIPv6 over HMIPv6, the operation in anticipation phase is simplified and simulation results show that hand-off latency can be reduced.

关 键 词：移动IPV6 快速移动IPV6 层次型移动IPV6
