Streaming Media Application Layer Multicast Model Based on Tree Ring

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.
