摘要
基于流的快速切换技术可以减少移动IPv6协议下行流的切换延迟。为此,提出一种新的基于流的快速切换方法,增强交叉路由器的功能,移动节点移到一个新位置只需要向交叉路由器注册,从而在交叉路由器和移动节点的新转交地址间建立隧道。分析结果表明,该方法能在一定程度上减少信令开销和会话中断时间,提高通信质量。
Flow-based fast handover technique is the improvement of mobile IPv6. It can reduce handover delay of downstream. Based on the analysis of flow-based fast handover technique, a new flow-based handover scheme is proposed. It enhances the functions of Crossing Router(CR). When Mobile Node(MN) moves to a new location, it only need to bind to CR. Thus a tunnel can be established between CR new care-of address of mobile node. Model analysis shows that the scheme can reduce the signal cost and conversational interrupt time, and improve the quality of communication.
