【摘要】：摘要：现今社会中,对于网络的管理已经发展到智能化、可视化,各种应用对网络管理提出了更高的要求。网络拓扑自动发现是网络管理实现故障快速发现和准确定位的重要参考。由于网络拓扑变得更加复杂,人工维护网络拓扑越发困难,自动发现网络拓扑结构的需求更加强烈。如何智能、快速、完整的获取网内设备数据是实现拓扑自动发现的基础。本论文研究分析了如何在复杂的现场生产环境中智能地获取网内设备数据,网络拓扑结构发现的方法。本课题来源于企业中的项目,该项目现已在国内某电信运营商上线。文章首先介绍了课题的研究背景以及国内外对网络拓扑发现和设备数据获取方法的研究现状,然后分析了智能获取设备数据的方法途径,之后对本系统中用到的网络拓扑发现原理进行了介绍,最后总结了现场生产环境的特殊问题和解决方案。文章接着给出了安全域核查系统的总体设计,该系统分为六个模块：初始化模块、数据采集模块、拓扑发现引擎模块、安全对象核查模块、拓扑图展现模块、核查任务结果展示模块。随后详细介绍了数据采集模块、拓扑发现引擎模块的实现。文章最后给出了在局域网中对安全域核查系统的测试结果。结果表明,本系统能够快速、完整地核查该测试网络内的设备,构建出该网络的网络拓扑图,并且服务器资源的消耗代价也符合要求。
[Abstract]:Absrtact: in today's society, network management has been developed to intelligent, visual, various applications to network management put forward higher requirements.Automatic discovery of network topology is an important reference for network management to realize fast fault detection and accurate location.Because the network topology becomes more complex and it is more difficult to maintain the network topology manually, the demand for automatic discovery of the network topology is more intense.How to intelligently, quickly and completely acquire the equipment data in the network is the foundation to realize the topology automatic discovery.This paper studies and analyzes how to intelligently acquire the equipment data and discover the network topology in the complex field production environment.This topic comes from the project in the enterprise, this project is now on line in a domestic telecom operator.This paper first introduces the research background of the subject and the research status of network topology discovery and device data acquisition at home and abroad, and then analyzes the methods of intelligent acquisition of device data.Then the principle of network topology discovery used in this system is introduced. Finally, the special problems and solutions of field production environment are summarized.The system is divided into six modules: initialization module, data acquisition module, topology discovery engine module, security object verification module, topology display module.Verification mission results display module.Then the implementation of data acquisition module and topology discovery engine module are introduced in detail.Finally, the test results of the security domain verification system in LAN are given.The results show that the system can quickly and completely verify the equipment in the test network, and construct the network topology diagram of the network, and the cost of the server resources is also in line with the requirements.
