【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】 In order to solve the problem of excessive download of digital resources in university libraries, a digital resource monitoring and management system based on network bypass monitoring technology is designed. 【Application Background】 There are some defects in the solution of the existing over-downloading problem. To remedy these defects, an optimized solution based on the bypass monitoring technology is proposed. 【Method】 This paper introduced the design of bypass constrained digital resource overloading by introducing bypass monitoring technology. Taking the digital resource monitoring system of Dalian University of Technology as an example, the paper explained the technical support principle, design idea and function module solution of the system. 【Result】 Under the premise of not affecting the original network topology and usage habits, the reader can accurately identify and record the reader’s access to digital resources, and warn and even block the suspicious users who download overloaded. 【Conclusion】 The digital resource monitoring system based on bypass monitoring method can accurately monitor the digital resources and effectively prevent the occurrence of excessive download events.
