摘要: 针对目前Internet组通迅技术的现状, 通过分析传统的多播机制与目前已有的应用层多播机制的特点, 设计出一种新的高效应用层多播方式(MCALM算法), 提出了网格建立算法、 网格维护算法和在网格上建立多播树的生成算法, 并进行了Java实现. 结果表明, 所提出的算法能较好地调整网格结构, 迅速优化网格和获得接近于IP多播的效率

关键词: 多播, 应用层多播, 网格, 多播树

Abstract: Facing to the current problems in Internet group communication, we analyzed the characters of traditional multicast mechanism and application level multicast mechanism, designed a new efficient application level multicast approach, proposed meshconstruction algorithm, mesh maintenance algorithm and multicast tree formation algorithm on mesh, and implemented it based on Java. The experiment results show the mesh structure can be set better by application level multicast, quickly improve the mesh performance and obtain higher efficiency than IP multicast.

Key words: multicast, application level multicast, mesh, multicast tree
