基于树环结构的流媒体应用层组播模型的研究

Streaming Media Application Layer Multicast Model Based on Tree Ring

该文首先分析应用层组播协议,结合流媒体在Internet上的特点,提出了流媒体树环模型。该模型基于NICE协议之上,综合衡量节点自身及链路因素权重,构建适用于大规模实时流媒体的树环应用层组播模型。模拟实验表明,该模型能够最大化资源利用率和最小化控制开销,可以很好地满足实时流媒体中大内容传输的需要。

By analyzing application layer multicast protocol,and the characteristics of streaming media in Internet,this paper had approved a multicast model of Tree Ring.This model which is based on the NICE has considered Comprehensively the node it self and link factor,and had used to application layer multicast suitable for large_scale streaming media.Simulation experiments show that the strategy will improve resource utilization,low control overhead,and satisfy the requirement of large_scale content transfer in real streaming media.
