摘　　要：为减小MIPv6网络切换时延,保证实时性要求高的语音、视频等业务的服务质量,针对MIPv6网络中,DAD操作时延严重影响网络切换性能的问题,提出一种减少DAD操作时延的方法。该方法将PIM和MLD协议用于FHMIPv6,并分别对微移动和宏移动中组播组的创建方法进行改进,利用仿真软件NS-2进行实验。实验结果表明,改进的方法减少了重复地址检测时延,降低了丢包率,提高了MIPv6网络切换性能。To reduce the handover latency and ensure real-time requirements quality of voice and video services in mobile IPv6 network, a method is proposed to solve the problem that duplicate address detection operational delay badly impacts on network handover performance in mobile IPv6 network. PIM and MLD protocol are used for FHMIPv6. Methods of creating multicast group are improved in the micro-mobility and macro mobility. The experiment makes use of simulation software NS-2. The re sults show that the improved method decreases DAD delay, reduces the packet lost rate and improves handover performance of mobile IPv6 network.
