| 摘 要： | 针对现有的多协议标签交换(MPLS)和层次移动IPv6(HMIPv6)融合的方案仍然存在时延大、丢包率高等问题，提出了一种改进的基于MPLS的HMIPv6方案。本方案通过将多播技术应用于移动锚点(MAP)，并且在切换完成之前提前完成新链路上标签交换路径(LSP)的建设，实现了移动节点(MN)移交切换时延的最小化，使得在切换过程中大大降低服务中断现象，最大限度地保证新链路建立完成之前数据包不被丢失。最后通过NS-2仿真与比较，结果表明本方案跟现有方案相比能够大大减少移动过程中的丢包率和传输时延，提高移动IP

| Abstract: | This paper proposed an enhanced scheme for hierarchical mobile IPv6 based multi protocol label switching(MPLS) to solve the problems of long latency and high packet loss for existing integrating MPLS with HMIPv6.This schemei applied the multicast technology to mobile anchor point(MAP),and completed the construction of LSP on new link in advance of the completion of handoff,achieve the goal of minimizing the MN's handoff latency,significantly reduced the service interruption in the process of handoff,guarant... |
