摘要
为了提高分级移动IPv6模型对于移动定位点出错后的恢复能力,对分级移动IPv6模型进行改进,提出了一种冗余的分级移动IPv6模型.通过在移动节点与多个移动定位点间建立隧道,提高移动定位点出错后移动节点与通信节点和家乡代理之间的错误恢复能力.另外采用主动探测的方式,提高发现移动定位点出错的能力,进一步提高了移动IPv6应对移动定位点出错后的恢复能力,提高分级移动IPv6的可靠性.最后通过模拟验证了相对于传统分级移动IPv6,本文模型能将MAP错误恢复时延减少65%.
In hierarchical mobile IPv6（HMIPv6）, the failure of mobile anchor point（MAP） will cause service interruption and long delays which result in a user perceptible deterioration in real time traffic. To reduce this affection, we enhanced HMIPv6 and proposed hierarchical mobile IPv6 （RD-HMIPv6） with redundance. The author＇s proposal improved the failure recovery ability by establishing IP tunnel between mobile node and several MAPs. In addition, active probing was used to reduce the delay of detect false MAPs. After the performance was simulated by using network simulator（NS-2）, the performance testing for the proposal was analyzed by comparing it with the basic HMIPv6. In conclusion, the results showed that the provided scheme can reduce the failure recovery delay of MAP compared with HMIPv6.
