摘要
在分层结构的基础上提出了一种基于优先级的ALM管理模型PBHM。该模型以分层结构为基础,具有控制开销小,高效、分布式的构建,更好的扩展性,以及无须任何底层拓扑信息等优点,且构建了PR IOR ITY数学模型来确定每个组成员的优先级。另外,通过仿真实验测试了系统性能,验证了相关结论。本模型能够更好地对用户进行管理和提高应用层组播的转发效率。
This paper proposed a priority-based hierarchical ALM management model （PBHM）. Because it is grounded on hierarchy, the model has many merits, such as little control overhead, high efficiency, distributed build, better expansibility, independent topology of bottom and so on. Further more, set up priority mathematical model in order to calculate the priority of each group member, in addition, test and proved the correlative conclusions by simulation experiment, therefore, the model increases the forwarding efficiency of ALM and administers its consumers in a more efficient way.
