摘要: 在层次移动IPv6中,当移动节点(MN)和通信对端(CN)之间存在更短路由时,二者之间的通信分组仍然要通过移动锚点(MAP)转发,造成了不必要的分组传输时延及系统开销;并且其按照先后顺序进行的域间绑定更新过程有一定的绑定更新时延。为此提出一种改进型层次IPv6,将路由优化分组通信技术应用于层次移动IPv6中,使用条件是分组传输与绑定更新数目比(PBR)达到给定的临界值;同时改进了域间切换的绑定更新流程。理论分析表明,改进型层次移动IPv6相对于层次移动IPv6在系统开销、绑定更新时延及分组传输时延等方面均有优势。

Abstract: In Hierarchical Mobile IPv6(HMIPv6), even though there is a shorter route between Correspondent Node(CN) and Mobile Node(MN),all the packets between them are still be forword by Mobility Anchor Point(MAP),it brings needless system's consumption and delay on packet transmission,and its binding update process of inter-region handover which conduct orderly has a certain delay on binding update.Therefore,an enhanced HMIPv6 is proposed,in which route optimized communication technology is applied when the number ratio of packet transmission to binding update reach a given threshold;Simultaneously, the binding update process of inter-domain handover is improved.A mathematical performance analysis proved that this enhanced HMIPv6 has advantages in reducing system’s consumption, delay on packet transmission and binding update in contrast to HMIPv6.
