移动IP中基于分布式注册服务器的指针优化策略

1.引言移动IP是一个在互联网上支持移动性功能的网络层解决方案,可以使移动节点以一个永久IP地址接入到任何网络上,并实现将IP包路由到位置不断改变的移动节点上。标准移动IP协议和路由优化协议都是通过家乡代理实时维护对移动节点的绑定来实现网络层的移动性管理。家乡代理中集成了数据传输和移动性管理功能,对所注册节点执行代理ARP,维护移动绑定,截获并封装转发分组,使家乡代理的

The Pointer Optimization Strategy Based on the distributed RSs in the Mobile IP Network

Mobility management is one of the key problems in the mobile communication techniques. The performance of the mobile communication networks is heavily depended on the effectiveness of the mobility management. In this paper, we have presented a protocol of the mobility management in the mobile IP networks, based on the distributed RSs. When the mobile user in the inactive connection handoffs, some pointers are constructed and modified by the RSs and routers. It can realize the local registration; only when a call arrives, the possible update operations of the mobile database are needed. Consequently, the access of the RS is limited, and the cost of the mobility management is also reduced.
