移动IPv6快速切换协议的分析和改进

Analysis and improvement of FMIPv6

分析了移动IPv6快速切换技术的预测式和反应式切换过程指出了移动IPv6快速切换协议解决此问题的缺陷,引入了层次型移动IPv6管理中的移动锚点思想,提出过渡期的概念及允许隧道链、防止隧道环的措施来解决和避免乒乓切换和三方切换问题,从而达到快速切换的理想时延和丢包率,实现无缝切换和满足实时通信及敏感业务的需求.

By detailly analyzed predictive and reactive fast handovers for mobile IPv6 , and deficiencies of FMIPv6 which to solve the above problems, the MAP idea of hierarchy mobile IPv6 is introduced. New concepts of transition, allowing tunnel chain and preventing tunnel ring are defined in the paper, which is designed to settle the problems of Pingpang handoff and triangle handovers. Analysis result shows that the scheme would be viewed as an effective method to obtain the perfect handover latency and packet loss rate, which will implement a seamless handoff, and satisfy the requirement of real time communication and sensitive business.
