利用旁路监听技术约束数字资源过量下载

Using Sniffer Technology to Constraint Electronic Resource Excessive Downloading

【目的】为解决高校图书馆存在的数字资源过量下载问题,设计基于网络旁路监听技术的数字资源监控管理系统。【应用背景】现有过量下载问题的解决方案中存在一定的缺陷,为弥补这些缺陷,提出基于旁路监听技术的优化解决方案。【方法】引入旁路监听技术方式探讨图书馆约束数字资源过量下载的设计思路,以大连理工大学图书馆数字资源监控系统为例,阐述系统的技术支撑原理、设计思路及功能模块解决方案。【结果】在不影响原有的网络拓扑和使用习惯的前提下,准确识别并记录读者对数字资源的访问下载情况,对过量下载的可疑用户进行警告提醒乃至屏蔽阻断。【结论】基于旁路监听方式的数字资源监控系统可以对数字资源实施准确监控,有效防止过量下载事件的发生。

[Objective] To solve the problem of excessive downloading of digital resources in university libraries, design digital resource monitoring and management system based on the network sniffer technology. [Context] There are some defects in the existing solutions for the excessive downloading problems. To compensate for these defects, the optimization solution scheme based on the network sniffer technology is proposed. [Methods] This paper introduces network sniffer technology to constraint electronic resource excessive downloading. Taking the digital resource monitoring and management system of Dalian University of Technology Library as an example, it describes the technical support principles, design thinking and modules achievement. [Results] Under the premise of not affecting the topology structure and users＇ habits of the original network, this system can identify and record the readers＇ access and download to electronic resources, and can finally effectively prevent the occurrence of the event of excessive downloading by warning and even blocking the shield of the suspect users of excessive downloading. [Conclusions] The digital resource monitoring system based on the sniffer technology can accurately monitor the digital resources and effectively prevent the occurrence of the event of excessive downloading.
