现有的移动IPv6切换机制依然存在切换时延大,分组丢失等问题。移动IPv6切换的关键问题是移动检测,本文提出了一种自适应主动预测邻居切换移动IPv6切换机制,采用主动自适应预测算法,根据网络和移动主机的运动状态智能的预测主机的切换,实现快速平滑切换。实验结果表明,该机制大大减少了切换时延和切换次数,提高了系统的切换性能,保证了网络的QoS。 The existing mobile IPv6 switching mechanism still has the problems of large switching delay and packet loss. The key problem of mobile IPv6 handover is mobile detection. In this paper, an adaptive active prediction neighbor switching mobile IPv6 switching mechanism is proposed. Active adaptive prediction algorithm is adopted. According to the intelligent predictive host switching between network and mobile host, Smooth switching. Experimental results show that this mechanism greatly reduces the switching delay and the number of handovers, improves the switching performance of the system and ensures the QoS of the network.
