摘要在传统的电视传输系统中，所有的频道都被推送到用户。因此，像频道切换这样的用户活动对提供商网络没有影响。因此，电视提供商认为没有强烈的需要来分析和调查他们的订户的行为。然而，在IPTV网络中，情况完全不同。用户的信道切换行为给网络带来了额外的负载，因此值得研究和分析。在本文中，我们阐述了IPTV用户建模的要求，并提出了一个模型，考虑到需求。该模型使用LoadSpec工具实现。我们提出的模型可以产生，在一个现实的方式，一个典型的IPTV客户端在一个活跃的会话切换事件的工作量。所提出的模型的IPTV分析，特别是，呼叫阻塞概率的评估的应用程序是由两个案例研究。
Abstract In traditional TV delivery systems, all the channels are pushed toward the subscribers. Therefore, user activities like channel switching have no effect on the provider network. Consequently, TV providers have felt no strong need to analyze and investigate the behavior of their subscribers. In IPTV networks, however, the situation is quite different. Channel switching activity of users imposes extra load on the network and therefore is worth to be investigated and analyzed. In this paper we elaborate the requirements of IPTV user modeling and propose a model taking into account the requirements. The model is implemented using the LoadSpec tool. Our proposed model can produce, in a realistic manner, the workload of switching events of a typical IPTV client during an active session. The application of the proposed model for the IPTV analysis, specifically, for the evaluation of the call blocking probability is shown by two case studies.
