摘要

由于移动IPv6方法的帮助,当移动节点在世界某个地方改变其附着点时,它可以有效地保持其与互联网的ip层连接。在切换过程中,由于移动节点的L2和L3切换操作,移动节点无法发送甚至接收IPv6报文。在本文中,作者讨论了不同类型的切换,给出了IEEE 802.11的快速切换,增强的WLAN切换和快速移动IPv6方法。每个实现都配置为访问一个与特殊SSID字符串相关的点,该字符串在后台提供有关附加AR前缀的所有信息。每当移动节点预测到即将发生的切换时,切换工具就会自动通知新AP的前缀。这样,移动节点就可以使用新AP的信标消息中携带的路由器前缀信息,在新子网上对新IP地址进行“预期”配置。

Link-layer support for fast mobile IPv6 handover in wireless LAN based networks
Due to the assistance of the mobile IPv6 approach, a mobile node can effectively maintain its IP-layer connectivity to the Internet when it changes its point-of-attachment somewhere in the world. During the accomplishment of the handover, the mobile node is unable to send or even receive IPv6 packets, both due to its L2 and also L3 handover operations. In this paper, the author discussed the different types of handovers, given as fast handover for IEEE 802.11, enhanced WLAN handover, and fast mobile IPv6 approach. Each implementation is configured to access a point involved with a special SSID string that provides all the information about the prefix of the attached AR in the background. Whenever the mobile node anticipates some upcoming handoff, the handover-tool is automatically informed about the prefix of the new AP. In that way the mobile node performs "anticipative" configuration of the new IP address on the new subnet by using the router prefix information carried in the beacon message of the new AP.
