改进的分层移动IPv6网络中快速切换方法

分层移动IPv6加入移动锚点来管理同一域内的移动，减少注册开销，从而能极大地减少切换延迟。但对于不同域间的移动，这种分层的结构并不能很好地解决切换延迟。提出一种分层移动IPv6网络中基于流的快速切换方法，将业务流状态分析与分层结构的思想有效地结合起来，有助于减少切换延迟以及丢包率。分析结果表明，该方法比现有的分层移动IPv6以及基于流的快速切换方法有着更好的性能。

Improved fast handover method for hierarchical mobile IPv6 network

Hierarchical Mobile IPv6 adds MAP to manage the movement within the same domain, thus minimizing the registration cost and greatly reducing the handover latency. But when it comes to the movement between the different domains, this hierarchical structure cannot efficiently solve the handover delay. In this paper, a new flow-based fast handover method for HMIPv6 network was presented. It combined the analysis of the flow state information and the Hierarchical structure to help reducing the handover delay and the rate of the packet loss. The analysis shows that this new method has better performance than the existing HMIPv6 method and flow-based fast handover method.
