| 摘 要： | 为了准确评估上海电信IPTV系统引入P2P机制后的效果,实现一个CDN-P2P混合架构的IPTV实时图示可扩展仿真系统RGSS(Real-time Graphical Scalable Simulator)。RGSS采用基于消息的事件驱动引擎,支持大规模节点仿真且具有实时可视化功能。实验表明,RGSS在进行大规模节点仿真时,不仅保证了高准确性,而且有效降低了资源消耗,提高了仿真效率。

| Abstract: | In order to accurately evaluate the effect of P2P policy being introduced in Shanghai Telecom IPTV system,this paper implements a hybrid IPTV simulator based on P2P-CDN RGSS(Real-time Graphical and Scalable Simulator).RGSS uses message-based event-driven engine with large-scale simulation supported and real-time visualisation.Experiment shows that the RGSS can guarantee the high precision as well as effectively reduce the resource consumed when in large-scale simulation,and improves the efficiency as well. |
