摘要:

提出了基于非齐次泊松过程的宽带拨号上网(ADSL)用户上下线模型.对用户上下线行为进行建模,并基于现网真实数据,使用模型计算用户24 h内的每时刻退出登录的平均概率,将模型的预测值与现网实测数据进行对比,分析了不同用户组退出登录概率一天内的变化和持续在线平均概率的变化.分析结果表明,提出的ADSL宽带用户上下线模型可以有效、量化地描述用户上下线行为,在ADSL宽带用户上下线行为的异常检测和舆情分析等领域具有较好的工程应用价值.

关键词: 上下线, 用户行为, 泊松过程, 随机过程

Abstract:

A model of asymmetric digital subscriber line (ADSL) on-off-line behavior based on non-homogeneous poisson process is presented. First, a model of ADSL on-off-line behavior is established by formula deduction. Then, the model is used to analyze and calculate the user average probability of logout based on real data from ADSL network. The value is predicted by using the model and analyzed by contrasting with real data. Finally, the change of average probability of logout and continued online in different user group are given by the model. The analysis result shows that the model could give a quantitative description of On-off-line behavior of network users effectively, and will make great effort to anomaly detection for ADSL on-off-line behavior and public opinion survey.

Key words: on-off line, user behavior, poisson process, stochastic process
