| 摘 要： | 分层移动IPv6与快速切换结合具有较好的切换性能,但是链路层中断不可避免,因此有效的缓存管理机制在FHMIPv6中仍然十分重要.根据快速分层移动IPv6的特点提出了一种有效的缓存管理策略,对比快速切换协议的缓存管理机制,该策略将MAP引入到系统的缓存管理中,从而提高了整个系统的缓存利用率.用NS-2模拟表明,该策略大大降低了切换过程中的丢包率,并减少了实时应用和高优先级包的切换延迟时间.

| Abstract: | With the combination of Hierarchical Mobile IPv6 and Fast Handover mechanism,the handover latency caused by layer 3 and up can be greatly minimized.However,the handoff latency resulted from link layer handover procedure is unavoidable,so an effective cache management mechanism is still important for FHMIPv6.The paper proposes an effective scheme of cache management by FHMIPv6 protocol.Compared with the cache management scheme of Fast Handover protocol,the scheme introduces MAP to the cache management,and the cache utilization is improved.Using the ns-2 simulator,it has demonstrated the effectiveness of our proposed scheme. |
