> 中文摘要: 提出了一种具有拓扑感知能力的拓扑簇模型TCM(topology-aware clustering model),并在此基础上提出了一种有效的应用层组播方案TCMM(TCM-based multicast).TCMM能够将一些相近的节点组织在一个拓扑簇中,从而在一定程度上实现了数据包的本地传输,并能缓解不同加入顺序对转发树的不利影响.分析和实验结果表明,TCMM能够实现有效的聚簇,能够在不同的加入顺序下构造性能大体一致的转发树,并能在不同程度上改善其他一些组播性能指标.
Abstract:This paper proposes a topology-aware clustering model (called TCM). Furthermore, it proposes a TCM-based application layer multicast scheme (called TCMM). In TCMM, many nearby nodes are clustered, which localizes the transport of some nodes and alleviates the negative impact caused by different join sequences. Analysis and experiments show that TCMM can effectively group nearby nodes and build multicast trees with similar gross performance in different join orders. In addition, TCMM can improve some of other multicast performance in some degree.
