摘　　要：目前主要研究如何获得及时的L2(Link Layer)触发信息以保证FMIPv6的切换过程按照预先模式执行。然而并非所有的L2触发都对应一个确实的切换动作,虚报L2触发(False Alarm of L2 Trigger)将导致严重的额外切换开销。基于NS-2仿真平台的一组实验证实了该问题。在此基础上,通过分析设定的时间间隔内路由通告报文的子网前缀,提出一种及时发现虚报L2触发,即时启动重新接入原接入网络的方案,并验证了其有效性。Currently, the main studies are focused on how to acquire the timely 12 （link layer） trigger information so as to ensure the FMIPv6 handover process to be executed in terms of the proactive mode. Firing the L2 trigger however does not always correspond to an actual handover, and false alarm of L2 triggering will cause serious additional handover overhead. The experiments conducted on NS-2 simulation platform have verified this problem. On that basis, we propose a scheme which timely determines the false alarm of L2 triggering and instantly starts to re-access into the previous access network by the subnet prefix analysed and set included in router advertisement packets within the time intervals, its effectiveness is verified as well.
