Research on session length and user categorization in large scale P2P TV network

Abstract

Abstract: P2P TV system is getting more and more popular as a new TV service. In contrast with traditional cable and satellite TV system, the Internet-based P2P TV is more interactive, more open, and has wider sphere of influence. While getting some new experience that is different from traditional TV system, P2P TV users have exhibited some new characters of viewing behavior. In this work, it performs an in-depth study on session length of P2P TV user by analyzing the real data collected from the self-developed measuring tool named TVCrawler. According to the distribution characters of user session length, it puts P2P TV users into three categories：light viewers with 3~5 minutes of mean session length, medium viewers with 20~50 minutes of mean session length, and heavy viewers with 120~200 minutes of mean session length. It analyzes online number and arrival rate for different categories of users.

Key words: peer-to-peer based TV, crawler, network measurement, user session length

摘要： P2P TV已经成为一种越来越普及的新型电视服务平台。与传统有线电视相比较，基于互联网的P2P TV在影响范围、交互性和开放性等方面都具有巨大的优势。P2P TV用户在感受到不同于传统电视的收看体验的同时，也表现出了不同于传统电视用户的收看行为。在利用自主研发的测量工具——TVCrawler获取实际系统数据的基础上，对P2P TV用户的会话时长进行了深入研究。按照P2P TV用户会话时长的分布特点，将其分为轻度收看者、中度收看者和重度收看者三类，对应的平均会话时长分别为3~5分钟，20~50分钟和120~200分钟，并进一步分析了在各被测频道中，三类用户各自的在线人数和到达率。
