摘要/Abstract

摘要： 针对代理移动IPv6（PMIPv6）中域内切换时延较大的问题，提出了基于LMA的域内切换路由优化方法。在新方法中，当移动节点链接到的新的移动接入网关向LMA发送代理绑定更新（PBU）消息后，LMA向相关的移动接入网关回发通信绑定更新（CBU）消息。分析和仿真结果表明，优化方法实现了切换后由先前的优化路径平滑且快速地过渡到新的优化路径，从而新方法能够有效地减少切换时延同时降低了切换路由优化过程中包传递发生乱序的可能性。

Abstract: This paper proposes a new intra_domain handover route optimization approach based on LMA for proxy mobile IPv6. When new mobile access gateway which mobile node attached to sends PBU message to LMA, LMA sends back the change with CBU message to related MAGs in new approach. Analysis and simulation results show that optimization approach achieves a smooth and fast transition from the old optimized path to a new one after handover, as a result, new approach can efficiently reduce the handover latency as well as the possibility of out-of-sequence delivery problem during the handover route optimization procedure.
