基于IPv6技术的互联网多移动节点网关接入容量切换方法

Access Capacity Switching Method of Internet Multi Mobile Node Gateway Based on IPv6 Technology

针对基本移动IPv6管理协议在多移动节点网关接入容量切换时存在切换时延长、吞吐量较少的弊端,提出基于IPv6技术的互联网多移动节点网关接入容量切换方法。以基本移动IPv6切换过程为基础,利用链路层触发理论实现移动节点移动位置的预测,配置子网信息和转交地址,将缓存请求消息、缓存确认消息引用到优先缓存机制中,基于链路层支持,利用通信线路宽带完成移动检测,降低整个容量切换过程的延时。仿真分析结果表明:该方法在多移动节点网关接入容量切换时、路径缓存时以及节点传输过程中的延时较低,具备吞吐量较小且数值变化平稳优势。

Aiming at the disadvantages of prolonging the handover time and less throughput when the basic mobile IPv6 management protocol switches the access capacity of multi mobile node gateway, an Internet multi mobile node gateway access capacity switching method based on IPv6 technology is proposed. Based on the basic mobile IPv6 handover process, the link layer trigger theory is used to predict the mobile location of the mobile node, configure the subnet information and care of address, reference the cache request message and cache confirmation message to the priority cache mechanism, complete the mobile detection by using the communication line broadband based on the link layer support, and reduce the delay of the whole capacity handover process. The simulation results show that this method has the advantages of small throughput and stable numerical change.
