摘要 通过对移动IPv6(MIPv6)及其衍生机制和实际应用中网络部署的学习和研究,提出一种集成了快速分层移动(F-HMIPv6)、缓存方法和多播机制的基于多播机制的层次型网络移动IPv6切换优化方案(MMIPv6)以提高实时传输中的切换性能。运用NS-2分别对MMIPv6、MIPv6、FMIPv6和HMIPv6针对切换时延、丢包率、信令负载进行了模拟,通过对仿真结果的分析证明了MMIPv6在无缝切换速度、平滑性上都优于MIPv6、FMIPv6、HMIPv6,更适合于实时业务中的数据传输。 Mobile IPv6 (MIPv6) and its enhancement mechanisms and actual network deployment are studied to propse a new comprehensive evaluation based on multy-casting mechanism called multy-casting MIPv6 (MMIPv6), witch integrates Fast-Handover Hierarchical MIPv6 (F-HMIPv6) and multy-casting machanisms, in order to improves the seamless handover performance of real time traffic. The handover delay, packet loss and handover signal of MIPv6, FMIPv6, HMIPv6 and MMIPv6 are simulated and analyzed with NS-2. At lost, MMIPv6 has the better performance than MIPv6, FMIPv6 and H -FMIPv6 in handover speediness and smoothness, and is more suitable for seamless handover of real time traffic.
