远程教育网络行为信息的测量与分析

Measurement and analysis of web-based behavior information in distance education

本文应用计算机网络行为分析的理论与方法,研究远程教育网络行为信息的测量与分析的问题。首先,基于流量测量的方法建立了网络行为信息的测量系统;其次,对网络异常行为和正常行为的信息进行了定性分析;最后,把这些方法应用到具体的远程教育网络实例当中,对例子中的数据信息进行统计分析和数据挖掘,并分析其信息所反映的一些网络行为模式。

Network functions and services are very influential factors of learning support system in distance education based on network environment. It has close relations with the learning quality from the part of distance learners. Therefore, there is necessity to establish a quality information measurement system and conduct quality control to the web-based learning support system, analyze and process the information collected so as to regulate and control quality of the system.The author in this article has explored some issues concerning the framework design of network behavior information measurement system, information collection and analysis.He first introduces computer network behavior analysis method of research used in this approach from such three respects as the basic content of network behavior analysis research, measurement for network volume of flow and model of the volume of the flow. Then he introduces the framework and technology of network behavior measurement system based on the method of measuring the volume of flow. At last he introduces its application in normal, abnormal, and gathering network behavior analyses. The application of normal network behavior analysis should include control of the basic network functions, analysis the volume of flow of Packets and Bytes for the server, protocol analysis of the server's volume of flow, and analysis of the volume of flow in accordance with the Client/Server format.
