摘要
为实现对移动IPv6网络的有效管理,进行了基于动态指针链的移动IPv6网络管理研究。首先在快速切换移动IPv6(FHMIPv6)管理机制中引入了WiMAX802.16e协议接入网络的链路触发机制,给出了一种移动IPv6移动管理方案w-FHMIPv6。该方案不仅能改善切换过程的丢包率和切换时延,而且它需要的链路层信号和信息交互也较少,有利于快速切换的实现。其次针对链路层切换完成后的网络层移动管理,对w-FHMIPv6方案进行了改进,给出了I(mproved)W-FHMIPv6分布式注册移动管理方案。该方案结合分布式注册思想,通过引入一种动态指针链的选择注册机制,可以减少注册信令开销,从而保证整个网络的负载平衡。最后通过整体方案的网络仿真,分析了改进方案IW-FHMIPv6对网络性能的影响。
To realize the effect management of mobile IPv6 networks, a study on the mobile IPv6 management based on dynamic pointer chains was conducted. Firstly, the fast link trigger mechanism for the WiMAX 802.16 protocol＇ s access to networks was introduced into the mechanism of fast handover mobile IPv6 （FHMIPv6） management, and a mobile IPv6 management scheme called the w-FHMIPv6 was given. The scheme has ability to improve the packet loss rate and the handover latency, and is beneficial to realization of fast handover because it needs less link-layer signals and information exchange. Secondly, the w-FHMIPv6 management scheme was improved in the mobility management of the network layer after the handover of the link layer is finished, thus the distributed registration mobility management scheme, called the IW-FHMIPv6 was proposed. This scheme can reduce the cost of registe- ring signaling and ensure the load balance of the entire network by the combination of the distributed registration method and the selecting registering scheme of dynamic pointer chains. Finally, the impact of network performance was analyzed for the improved scheme IW-FHMIPv6 by the network simulation of the entire scheme.
