Internet信息采集技术研究

RESEARCH ON INTERNET INFORMATION HARVESTING

网络拓扑发现技术在网络建设与管理中的地位越来越重要,Internet信息采集技术是其中一个非常重要的研究内容。本文在建立信息采集模型的基础上,讨论Internet信息采集在信息收集、信息解析和信息分析三方面的关键技术,即信息收集的自动性优化技术、信息解析技术和空间实体映射技术。

The technology of network topology discovery is becoming more and more important in the fields of network security defence and management. As a part of the project, Information Harvesting provides vital information support for topology analyzing and displaying. This paper mainly discusses the technology of Information Harvesting. The author first models the implementation both in ideal condition and in practical condition, based on which the author analyzes the feasibility of information harvesting and the difficulties inside. Three important techniques are put forward in this paper which are how to optimize the collection is automatism, how to parse the information and how to map related items in different spaces.
