| 摘 要： | 提出了一种基于主机邻域密度的QoS保证的应用层多播模型MCT,模型设计为典型的树结构。主要阐述了多播节点的加入与退出过程,首先定义了主机邻域密度的概念,并以此为标准对所有节点进行初次择优,随后运用服务质量路由算法RDSS进行二次择优,得到多个网络参数限制条件下最满足QoS需求的接入路径,最终达到应用层多播(ALM)拓扑结构的整体优化。仿真结果证明,模型的建立方法可以平等且有效地控制多个网络参数,满足了ALM应用的QoS需求。 |

| Abstract: | This paper presented a QoS guaranteed application layer multicast(ALM) model,which called MCT(multiple constrains ALM tree),and designed as a typical tree structure.The paper focused on nodes joining and departure procedures,defined host-domain-density as the standard for the elementary selection,and RDSS QoS routing algorithm for further selection.It achieved an optimal access path constrained by multiple network parameters and an entire optimization of ALM topology.The simulation results show that the MCT method can control multiple network parameters equally and effectively,and can satisfy the required QoS of ALM applications. |
| Keywords: | application-layer multicast quality of service(QoS) multi-constrains routing decision support system(RDSS) host-domain-density |
