摘要
针对目前宽带网络应用中带宽紧张的问题,对 CDN 流媒体网络进行了研究,提出了一种新型的基于环路节点及 P2P 的 CDN 流媒体模型。通过使用 OPNET仿真软件研究该网络的流量。仿真结果表明该网络模型对于主干链路的流量压力相比 P2P+CDN 流媒体网络具有明显的改善。
In order to solve the tension of bandwidth in the application of broadband network, the CDN streaming media networks had been studied, a new CDN streaming media model based on loop nodes and P2P was designed. This network model was simulated by employing OPNET, and the network traffic was studied. Simulation results show that this model based on loop nodes and P2P has significantly improved in reducing the traffic pressure of trunk link than P2P ＋CDN streaming media network.
