| 摘 要： | 在CDN和P2P两种主流的流媒体分发技术的基础上，提出了基于系统流量的混合流媒体分发模型，根据系统中节点数量和媒体流量之间的关系，在CDN自治域内实现CDN和P2P的混合式服务，并对上述理论进行了仿真。实验结果表明，与传统的CDN和P2P相比，新的混合模型既可以减少主干网络的流量，又能在不降低流媒体质量的情况下，有效降低CDN服务器压力，减少系统的响应时间，提高网络利用率。

| Abstract: | Based on CDN and P2P, this paper provided a new HSDM. According to the relation of peers and streaming capacity in the system, realized and then simulated the hybrid model. The result shows that compared with traditional CDN and P2P, this new hybrid model obviously reduces the flow of backbone network. And also, with this new method can effectively reduce the pressure of CDN severs and the response time of system without compromising the media quality delivered, and increases the network utilization. |
