摘要:

代理移动IPv6是集中式的基于网络的移动管理协议,其本地移动锚点已成为限制网络规模的瓶颈. 为了解决这一问题,提出一种部分分布式移动管理方案,将本地移动锚点的前缀分配和路由功能分布至接入网络端的路由器上,接入路由器通过任播地址寻址到最靠近接入网络的数据库完成位置管理. 此外,当移动节点距离初始的接入网络过远、切换时延过长时,重启会话. 综合分析结果显示,此方案具有一定的可行性.

Abstract:

Proxy mobile IPv6 is a centralized network-based mobility management protocol. Its local mobility anchor has become the bottleneck of network size growth. To solve this problem, a partially distributed scheme of proxy mobile IPv6 is proposed, where the prefix allocation and routing function of local mobility anchor is distributed to the access network. The access router reaches a nearest database by an anycast address to manage location. Besides, when the mobile node is far from the initial access network and the handover latency is too long, the proposed scheme will restart flows connection. The comprehensive analysis shows the proposed scheme is feasible.

Key words: proxy mobile IPv6, distributed mobile management, partially distributed
