摘要
综合评价了多种移动IPv6扩展协议在基于端到端的TCP协议L3层的切换性能,模拟仿真了乒乓切换在MIPv6、FMIPv6、HMIPv6和FHMIPv6中的时延、吞吐量和丢包现象,提出了一种优化的FHMIPv6方案.该方案通过定义新的Hop-by-Hop选项报头TM、PCoA表和双向隧道表,实现MN的快速、平滑切换,比FHMIPv6进一步减少了时延,提高了吞吐量,降低了丢包率.
Considering lack of comparative studies on Ping-pong handover, a comprehensive evaluation was carried out to estimate the handover performance of layer-3 of TCP protocol based on end-to-end for various Mobile IPv6 extensions.Simultaneously,the latency,throughput and packets loss rate of ping-pong handover in classical mobile ~ protocols such as MIPv6,HMIPv6, FMIPv6 and FHMIPv6 are simulated. Based on which, a novel scheme, optimized FHMIPv6 is proposed. A new Hop-by-Hop option header named TM （Tunnel Message） header,PCoA Table and Tunnel Table are defined in this scheme to implement MN＇s fast and seamless handover. Compared with FHMIPv6, the new scheme can further reduce the handover latency and eliminate the possibility of packets loss as well as improve the whole throughput.
