> 中文摘要: 切换延迟和丢包率是决定移动组播算法是否能够满足实时性组播应用要求的重要指标.提出了一种基于邻居信息交换的组播快速切换算法M-FMIPv6/NIE.在二层触发器事件发生之前,通过邻居接入路由器之间定时的信息交换,可以提前进行新转交地址的配置和请求加入组播树等操作.性能分析和仿真结果表明,M-FMIPv6/NIE的组播服务中断时间小于现有的组播快速切换算法,并且在缓存数量和丢包率等方面也具有较佳的性能.
Abstract:The handover latency and the packet loss rate are important criterions that determine if the mobile multicast algorithm could adapt to real-time multicast appliances. This paper proposes a multicast fast handover algorithm based on neighbor hood information exchange (M-FMIPv6/NIE). Before L2 trigger event occurs, M-FMIPv6/NIE can configure new care-of-address (nCoA) and request new access routers (AR) to join multicast tree. The performance analysis and simulation results indicate that, the multicast service disruption time of M-FMIPv6/NIE is less than that of existing multicast fast handover algorithms and it has good performance in buffer size and packet loss rate.
