基于冗余路由信息和预缓存策略的移动IPv6快速切换方法

Fast handover scheme based on redundant router information and pre-buffering strategy for mobile IPv6

研究了FMIPv6(MIPv6 fast handovers)协议中移动节点在预测出错情况下的IP连接恢复问题,提出了一种基于冗余路由信息和预缓存策略的快速切换方法RIRS(router information redundancy scheme)。该方法通过构造冗余切换路由表来协助移动节点快速重构新的转交地址,并采用预缓存策略来保护切换过程中到达的数据分组。仿真结果表明,RIRS能够获得比FMIPv6更小的切换延迟及丢包率。

The issue of IP connectivity resumption in case of erroneous prediction was investigated in fast handovers for IPv6（FMIPv6） protocol.Based on the redundant router information and pre-buffering strategy,a new scheme called RIRS（router information redundancy scheme） was proposed.The scheme constructed redundant router table for handover in order to assist the mobile node to re-formulate a new care of address quickly,and employed pre-buffering strategy to protect the packets destined for mobile node during handover.Simulation results indicate that RIRS can achieve better performance in terms of handover latency and packet loss compared with FMIPv6.
