针对如何有效降低P2P Vo D系统发生VCR操作时产生的时延问题,提出了一种P2P Vo D系统中的两层关系预取策略,根据节点的播放记录找到片段之间可能存在的关系,以此为依据进行预取,并对节点的邻居列表进行优化,使之能更快定位和预取资源。...针对如何有效降低P2P Vo D系统发生VCR操作时产生的时延问题,提出了一种P2P Vo D系统中的两层关系预取策略,根据节点的播放记录找到片段之间可能存在的关系,以此为依据进行预取,并对节点的邻居列表进行优化,使之能更快定位和预取资源。仿真实验结果表明,两层关系策略准确地预取了视频内容,降低了VCR时产生的时延,提高了用户的观看体验。展开更多

Law enforcement authorities may intercept and record specific conversations with a court order and CDRs can be obtained from telephone service providers. However, the CDRs of a suspect for a period of time are often fairly large in volume. To obtain useful information and make appropriate decisions automatically from such large amount of CDRs become more and more difficult. Current analysis tools are designed to present only numerical results rather than help us make useful decisions. In this paper, an algorithm based on Fuzzy Decision Tree （FDT） for analyzing CDRs is proposed. We conducted experimental evaluation to verify the proposed algorithm and the result is very promising.展开更多
