摘要
首先介绍了一种改进的转交地址的配置方法,以便缩短移动IPv6切换中重复地址检测(DAD)的时间;然后介绍了目前移动IPv6常用的两种切换技术,即快速移动和分层移动切换技术;最后提出了一种新的基于可信区域的切换技术。利用OPNET对改进地址配置后的基于可信区域的切换方法进行仿真,并与通常切换方式进行比较。结果表明,基于可信区域的切换方法对乒乓式运动反复切换中绑定时间延迟、绑定信令在骨干网交互数目上都有很大的优化,从而提高了网络的性能。
Firstly, this paper introduced the new care-of address configuration method to reduce the DAD time. Secondly, introduced fast and hierarchical handoff methods commonly used in the mobile IPv6. Lastly, described a new handoff method based on the credible area for mobile IPv6. The simulation results of the new method in OPNET indicate the new handoff method based on the credible area for mobile IPv6 can optimize the delay and the number of the binding greatly in the pingpong movement, improve the performance of mobile IPv6.
