基于主机标识协议的增强型分布式移动管理

将宏观移动性管理的主机标识协议(HIP)应用于分布式移动性管理(DMM)构架，并将聚合服务器(RVS)与DMM中的移动性接入路由MAR功能集成于分布式接入网关(D-GW)。采用扩展HIP协议数据包头的参数，在注册D-GW的HIP BEX消息中携带切换前D-GW的主机标识符的二元组（HIT，IP地址），新D-GW根据此二元组信息向前一个D-GW注册并建立的隧道，将缓存在前D-GW中的数据转给新D-GW。这一切换机制可有效地保证数据完整性，仿真结果表明该方法能有效减少总的信令开销，同时基于HIP的移动性管理使节点的安全性得到了保证。

Enhanced distributed mobility management based on host identity protocol

The Host Identity Protocol (HIP) macro mobility management was introduced into Distributed Mobility Management (DMM) architecture, and Rendezvous Server (RVS) was co-located with the DMM mobility access routing functionality in Distributed Access Gateway (D-GW). By extending the HIP protocol package header parameters, the HIP BEX messages carried host identifier tuple (HIT, IP address) to the D-GW new registered, and the new D-GW forwarded the IP address using the binding massage. Through the established tunnel, data cached in the front D-GW would be later loaded to the new D-GW. This paper proposed a handover mechanism to effectively ensure data integrity, and the simulation results show that this method can effectively reduce the total signaling overhead. Furthermore, the security of HIP-based mobility management can be guaranteed.
