摘要
快速切换方案在降低切换延迟方面所取得的效果已经得到了公认,但其交互过程较为复杂,不利于该技术的大规模推广。针对该问题,文中结合分层移动IPv6提出了一种高效快速切换方案。该方案不仅通过缩短重复地址检测的时延进一步降低快速切换的切换延迟,还借助应用层和链路层的信息有选择的执行快速切换,从而既降低了切换延迟也简化了切换交互过程、降低切换注册中的消息流量。实验结果表明,本方案中注册开销和切换延迟均低于现有快速分层移动IPv6方案。
It is known to all that fast handover is the most effective scheme for mobile IPv6 to reduce handover latency. However,the interaction during fast handover is too complicated, which largely reduced the scheme＇ s popularity. Aimed at this problem, an efficient fast handover scheme for hierarchical mobile IPv6 is proposed in this paper. In this scheme, improved the interactions during fast handover, and run the fast handover procedure according to the information from link layer and application layer. The simulation results show the scheme reduces both the registration cost and handover latency ,compared with existing fast handover scheme.
