P2P文件共享系统行为特性模型分析
Modeling and analysis on behavioral characteristics of P2P file-sharing system
摘要
Abstract
Due to the properties of self Organization, behavior characteristics affect the reliability and performance in P2P file-sharing system significantly. In order to understand this nature, this paper investigated properties and distribution model of users ' behavior characteristics in MAZE system through statistical methods. And the results indicate that upload and download traffic, upload and download bandwidth of users' can be modeled by lognormal mixture distribution; active time and transmission time of users' can be fitted using the lognormal distribution; while the number of requests and the requested number of users' are modeled by the mixed exponential distribution and Pareto distribution.关键词
