摘　　要：在现有组播体系中,IP组播在部署和规模扩展等方面存在很多问题,覆盖组播的效率和健壮性有待改进,大量底层网络技术支持硬件组播,但得不到有效利用。该文提出一种节点自组织的多层组播体系结构(NSMM),将各层组播的优势进行有效整合,论述了NSMM的整体结构及核心组件,与现有体系作了对比分析。For nowadays multicast technologies,IP multicast is hampered by a host of unresolved problems such as deployment and scalability,overlay multicast is needed to be improved with concerns relating to performance and robustness,a large number of communication systems support hardware multicast,which has never been utilized effectively.This paper presents a novel architecture named Nodes Self-organized Multilayer Multicast（NSMM）to integrate the advantages of related technologies in different layers,introduces the primary design of NSMM,and compares it with existing multicast methods.
