【摘要】：在網(wǎng)絡技術飛速發(fā)展的社會背景下,接入網(wǎng)絡的信息基礎設施的數(shù)量逐年增加,網(wǎng)絡的結構變得更加復雜,規(guī)模也隨之更加龐大。而病毒與網(wǎng)絡攻擊等問題,更使得網(wǎng)絡管理變得越來越重要�；谶@種情況,Internet體系結構委員會(IAB)制定了基于TCP/IP的網(wǎng)絡管理協(xié)議-SNMP協(xié)議。簡單網(wǎng)絡管理協(xié)議(SNMP)作為TCP/IP協(xié)議簇的一部分,由于其簡單實用性和易實現(xiàn)性,得到了設備廠商的廣泛支持,已成為網(wǎng)絡管理事實上的標準,應用范圍十分廣泛。本文介紹了網(wǎng)絡管理系統(tǒng)的現(xiàn)狀及研究意義,針對某省級氣象系統(tǒng)網(wǎng)絡管理的需求,通過分析、介紹SNMP協(xié)議,對系統(tǒng)的設計提出了設計方案,并對主要使用的技術進行了介紹,實現(xiàn)了一個基于SNMP協(xié)議的網(wǎng)絡管理系統(tǒng)。對開發(fā)中遇到的重點和難點問題進行了分析和解決。針對網(wǎng)絡拓撲方面的應用需求,設計實現(xiàn)了一種基于SNMP代理機制的三層網(wǎng)絡拓撲發(fā)現(xiàn)方法;應用“多種方式,準確發(fā)現(xiàn)”的策略來保證設備發(fā)現(xiàn)的效率和準確性;通過分析設備變化后拓撲顯示不準確的問題,設計出了一種“后臺實時掃描”的服務程序來實現(xiàn)數(shù)據(jù)的實時更新。給出了基于SVG技術的圖形化網(wǎng)絡拓撲顯示模型,使拓撲顯示準確、美觀,并能實現(xiàn)拖動和超鏈接的功能。最后,對實現(xiàn)的網(wǎng)絡管理系統(tǒng)進行了測試,總結了不足之處。項目已經(jīng)通過了驗收,運行良好,基本達到了預期目標。
[Abstract]:With the rapid development of network technology, the number of information infrastructure connected to the network is increasing year by year, and the network structure becomes more complex and the scale becomes larger. And virus and network attack and so on, make network management become more and more important. Based on this situation, the TCP/IP based network management protocol (SNMP) was developed by the Internet Architecture Committee (IAB). As a part of TCP/IP protocol cluster, simple Network Management Protocol (SNMP) has been widely supported by equipment manufacturers because of its simplicity and practicability. It has become the de facto standard of network management and has a wide range of applications. This paper introduces the status quo and research significance of network management system. According to the demand of network management of a provincial meteorological system, this paper introduces the SNMP protocol through analysis, puts forward the design scheme of the system, and introduces the main technology used. A network management system based on SNMP protocol is implemented. The key and difficult problems encountered in the development are analyzed and solved. According to the application requirements of network topology, a three-layer network topology discovery method based on SNMP proxy mechanism is designed and implemented, and the strategy of "multiple ways, accurate discovery" is applied to ensure the efficiency and accuracy of device discovery. By analyzing the problem of inaccurate topology display after equipment change, a kind of "background real-time scanning" service program is designed to realize the real-time updating of data. This paper presents a graphical network topology display model based on SVG technology, which makes the topology display accurate and beautiful, and can realize the functions of drag and hyperlink. Finally, the network management system is tested and the shortcomings are summarized. The project has passed the acceptance inspection, running well, basically reached the expected goal.
