3TNet视频点播系统中用户点播行为仿真及应用

通过分析3TNet视频点播（VOD）系统中的媒体服务情况，集中研究了用户点播模式、媒体热度分布，根据实际系统中用户点播分布的研究结果构建了一个用户点播行为的仿真平台。该平台描述了用户点播行为的一般数学模型，刻画了用户进入系统的行为分布特点。实验表明，VOD用户点播行为仿真平台能够客观真实地反映用户的点播行为，并通过构建一个仿真的视频点播系统来验证此平台的可用性，利用此仿真视频点播系统比较了两种部署策略的优劣。

Simulating User Behavior of Video-on-demand Systems of 3TNet and Application

Analyzing media server of 3TNet video-of-demand(VOD)system,the study focuses on user access patterns,popularity distribution,with the result,a simulation platform for user behavior was proposed.A general mathematics model for user behavior in VOD system was built to present the distribution of user visiting action.The simulation indicates that the platform objectively reflects the user action in VOD system,and using this platform simulates a VOD system to prove its usability,comparing two deploy algorithms'...
