摘　　要：和目前WCDMA/GPRS、WLAN网络中的移动性相比,移动IPv6是一种网络层移动性解决方案,具有一定的优势,如垂直切换.但是移动IPv6的切换性能和安全性影响了其商业部署,提出了一种将快速切换和AAA结合起来的机制,并在基于网络处理器的接入路由器和Linux主机上实现了该方案.实验表明,该方案具有较小的切换时延.Mobile IPv6 figures out mobility management in network layer. Compared with mobility in WCDMA/GPRS and WLAN environments, Mobile IPv6 has advantages in some features such as vertical handoff. However, the handoff performance and security of Mobile IPv6 affect its commercial deployment. This paper proposes a method by which fast handoff and AAA can be used jointly in Mobile IPv6. The method is implemented on access router based on network processor and Linux machines. Finally, experiment results show that the system can achieve low latency handoff.
