| 摘 要： | 近年来对P2P网络电视流量及其行为特征进行测量已成为1个重要的研究领域。但当前的P2P流测量研究主要侧重于P2P文件共享系统,对于P2P网络电视的研究则偏重于对某单一应用的分析。文中针对以上问题从流到达的间隔时间与流到达率两方面,对当前最流行的4种P2P流媒体软件进行基于统计建模的流测量研究。结果表明:P2P网络电视的实时性要求以及用户行为的相似性使各种P2P流媒体流量具有相似的流量模型且具有重尾特征。

| Abstract: | In recent years,measuring P2P IPTV traffic and studying its behavior characteristics have become an important field.However,the present work on measuring P2P traffic mainly focuses on P2P file-sharing systems or on a special type of P2P applications.In view of this,we measure P2P IPTV flows based on statistical modeling of the most popular four types of P2P IPTV applications in the fields of flow arrival rate and flow inter-arrival time.Our results show that because P2P IPTV users behave similarly,the flows... |
