摘　　要：切换时延和数据包丢失一直是制约移动IPv6发展的关键因素。文章针对现有切换算法及存在的问题进行了分析,然后在现有算法的基础上提出了一种改进算法。仿真实验结果表明,该算法能有效地抑制因移动节点的网络切换而导致的通信节点拥塞控制机制的启动,提高了移动网络数据流的正确率和吞吐量,进而提高了移动网络的通信质量。Handoff delay and data packet loss are always the key factors in restricting the development of mobile IPv6. In this paper, the problems with the existing handoff algorithms are analyzed, on the basis of which an improved algorithm is presented. Simulation results show that by this new algorithm the initiation of the control mechanism for the communication node congestion arising from the network handoff of the mobile nodes can be effectively restrained so that the correctness and throughput of the mobile network data stream are increased and the communication quality of the mobile network improved.
