摘　　要：基于新的网络流定义,将多维数据模型技术应用于网络流量分析,提出了网络流多维数据模型(NF-MDM)。详细定义了NF-MDM的事实和维表,建立了网络流的星型数据模型和多维立方体,实现了一个基于NF-MDM的多维网络流量分析系统。该模型用于分析网络流量时,角度更清晰,方式更灵活,已经应用在某高端商用网络流量分析设备中。By applying the multidimensional multilevel data model to network traffic, a new definition of network flow is provided, which is called the network flow multidimensional data model or NF-MDM for short. This paper clearly defines the fact table and dimension tables of NF-MDM, and then establishes the star schema and multidimensional cube of network flows, and then analyzes the network traffic by aggregation, slice, dice, drill-down, roll-up. The experiments indicate that the NF-MDM provides clearer angles and more flexible methods for metwork traffic analyses. A multidimensional network traffic analysis system based on the NF-MDM has been implemented and applied to some kind of high-end commercial network traffic analysis equipments.
