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。

Abstract: 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.

Key words: multicast, multilayer forwarding, Nodes Self-organized Multilayer Multicast(NSMM)
