摘要 为了解决移动IPv6节点进行远程小区移动时的性能优化问题,提出了基于分级机制的优化移动IPv6模型,对面向小区移动的分级管理机制(HMIPv6)进行改进,通过引入域边缘路由器并设计自适应绑定更新策略和传递绑定匹配算法使得HMIPv6下的三角路由问题得到解决,优化了移动节点的性能·另外,模型根据移动节点的通信伙伴(CN)所处位置,提出了内部CN处理策略,进一步降低了内部CN与移动节点间的通信开销,使模型对网络环境的变化具有较强自适应能力,提高了网络资源利用率·实验系统验证了模型的有效性· An optimal mobile IPv6 model based on hierarchical mechanism is proposed to optimize the performance of localized mobile node (MN) in remote region. The traditional hierarchical managing mechanism (HMIPv6) is improved through the proposed self-adapting binding update policy in which a map edge router (MER) is introduced with the passing binding match algorithm we designed and two new binding messages (binding update request, and binding update acknowledgement) provided. Thus, MER could directly intercept packets from or to MN to eliminate the triangle route within HMIPv6 and optimize the performance of MN. Moreover, the intra-CN processing policy is also proposed in terms of the location of correspondent node (CN) to reduce the communicating cost between intra-CN and MN. As a consequence, the model is capable of self-adapting to exterior network changes so as to improve the utilization of network resources. Finally, the prototype has verified the availability of the model.
