摘要: 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。

Abstract: 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.

Key words: Host Identity Protocol (HIP), Distributed Mobility Management (DMM), Host Identity Tag (HIT), signaling overhead, data integrity, handover
