摘要： 介绍了在移动通信中,利用主动网上中间结点的计算能力,实现一种双向、可优化、能更好地适应主机迁移的组播树算法——主动组播树算法。与其他组播树算法相比,这一算法在处理主机迁移时效率较高,端到端延迟比较稳定,而且不必在每次主机移动后重新建立组播树。这对移动网络的开发有着重要的理论意义和实用价值。

Abstract: In this paper, the authors mainly discuss the active multicast algorithm, which is AN-based tree that is bidirectional, optimizable and adaptive to host migration. Compared with other multicast algorithm, the algorithm is better in tree efficiency, end to end latency when handling with host migration.
