随着互联网络的快速发展,P2P文件共享系统已经成为了当今互联网流量的重要组成部分,是整个网络通信领域研究的热点之一。文件传播模型是研究P2P文件共享系统中节点行为特征最常用的一种方法。由于文件在网络中的复制传播与流行疾病在人群中传播有许多相似之处,运用系统动力学的理论与方法,建立一种基于SEIR的文件传播模型,能够从定性和定量两个方面分析和预测文件的复制传播趋势。

With the rapid growth of Internet,P2P file sharing system has become the important component of today's Internet traffic,thus,it is one of the research hotspots in the domain of network communication.The model of file-propagation is the most commonly used method in which the character of node behavior is studied in P2P file sharing system.Due to the similarity of the propagation character between file on network and the epidemic in crowd,the theories and methods of system dynamics are used to build a model of file-propagation in P2P file sharing system based on SEIR,the trend of file-propagation can be analyzed and forecasted from two aspects of qualitative and quantitative.
