基于瞬间绑定的PMIPv6协议的域间切换方案

AN INTER-DOMAIN HANDOVER SCHEME BASED ON TRANSIENT BINDING FOR PROXY MOBILE IPV6

摘要: 提出了一种采用逻辑接口的基于TPMIPv6（transient binding for proxy mobile IPv6）的域间切换管理方案．逻辑接口从2个物理接口抽象出来，上层只需知道这个逻辑接口，2个物理接口对上层透明．在切换时，2个物理接口分别与2个MAG（mobile access gateway）相连，后一接口在进行预注册时，前一接口仍保持原来的通信．流移动管理由LMA（local mobile anchor）控制，以避免切换过程中物理接口的中断．分析结果表明，与已有的域间切换方案相比，建议方案的切换时延更小．

Abstract: An inter-domain handover management solution is proposed based on transient binding for PMIPv6 (Proxy Mobile Internet Protocol version 6), using logical interface to configure IP address instead of using two physical interfaces. MN can keep communicate with others using logical interface through physical interface 1 when it is in pre-registration processing using physical interface 2. Flow mobility management is charged by LMA (local mobile anchor). Analysis result shows that the proposed scheme has lower handover latency compared with the existing global mobility management protocol.
