基于PMIPv6的域间切换管理方法及性能分析

Proxy mobile IPv6 based inter-domain mobility management approach and performance analysis

针对代理移动IPv6(PMIPv6)中域间切换时延较大的问题,提出了一种基于PMIPv6的域间切换管理方案。新方案通过在PMIPv6域间发送PBU绑定更新消息,使得切换目标PMIPv6域提前知道移动节点(MN)的家乡网络前缀,避免了移动节点参与移动性管理及重新配置转交地址,从而有效减小了切换时延。分析和仿真结果表明,与现有的全局移动性管理方案移动IPv6和快速移动IPv6相比较,新方案更加适应移动性管理中低时延、低复杂度、易于操作的要求。

This paper proposed an inter-mobility handover management solution for proxy mobile IPv6 （ PMIPv6 ）. Using the proxy binding update message between two PMIPv6 domains, the destination PMIPv6 domain was able to obtain the mobile node＇ s home network prefix in advance, therefore, the mobility management and the reconfiguration the care-of-address performed by the mobile node could be avoided, resulting in the efficient saving in handover latency. Analysis and simulation results show that the proposed approach for PMIPv6 inter-mobility provides better performance in terms of low latency, low complexity and easiness of management, etc. , compared with the existing global mobility management protocol, i. e. , mobile IPv6 and fast mobile IPv6.
