【摘要】：在網(wǎng)絡(luò)技術(shù)飛速發(fā)展的社會(huì)背景下,接入網(wǎng)絡(luò)的信息基礎(chǔ)設(shè)施的數(shù)量逐年增加,網(wǎng)絡(luò)的結(jié)構(gòu)變得更加復(fù)雜,規(guī)模也隨之更加龐大。而病毒與網(wǎng)絡(luò)攻擊等問題,更使得網(wǎng)絡(luò)管理變得越來越重要。基于這種情況,Internet體系結(jié)構(gòu)委員會(huì)(IAB)制定了基于TCP/IP的網(wǎng)絡(luò)管理協(xié)議-SNMP協(xié)議。簡(jiǎn)單網(wǎng)絡(luò)管理協(xié)議(SNMP)作為TCP/IP協(xié)議簇的一部分,由于其簡(jiǎn)單實(shí)用性和易實(shí)現(xiàn)性,得到了設(shè)備廠商的廣泛支持,已成為網(wǎng)絡(luò)管理事實(shí)上的標(biāo)準(zhǔn),應(yīng)用范圍十分廣泛。本文介紹了網(wǎng)絡(luò)管理系統(tǒng)的現(xiàn)狀及研究意義,針對(duì)某省級(jí)氣象系統(tǒng)網(wǎng)絡(luò)管理的需求,通過分析、介紹SNMP協(xié)議,對(duì)系統(tǒng)的設(shè)計(jì)提出了設(shè)計(jì)方案,并對(duì)主要使用的技術(shù)進(jìn)行了介紹,實(shí)現(xiàn)了一個(gè)基于SNMP協(xié)議的網(wǎng)絡(luò)管理系統(tǒng)。對(duì)開發(fā)中遇到的重點(diǎn)和難點(diǎn)問題進(jìn)行了分析和解決。針對(duì)網(wǎng)絡(luò)拓?fù)浞矫娴膽?yīng)用需求,設(shè)計(jì)實(shí)現(xiàn)了一種基于SNMP代理機(jī)制的三層網(wǎng)絡(luò)拓?fù)浒l(fā)現(xiàn)方法;應(yīng)用“多種方式,準(zhǔn)確發(fā)現(xiàn)”的策略來保證設(shè)備發(fā)現(xiàn)的效率和準(zhǔn)確性;通過分析設(shè)備變化后拓?fù)滹@示不準(zhǔn)確的問題,設(shè)計(jì)出了一種“后臺(tái)實(shí)時(shí)掃描”的服務(wù)程序來實(shí)現(xiàn)數(shù)據(jù)的實(shí)時(shí)更新。給出了基于SVG技術(shù)的圖形化網(wǎng)絡(luò)拓?fù)滹@示模型,使拓?fù)滹@示準(zhǔn)確、美觀,并能實(shí)現(xiàn)拖動(dòng)和超鏈接的功能。最后,對(duì)實(shí)現(xiàn)的網(wǎng)絡(luò)管理系統(tǒng)進(jìn)行了測(cè)試,總結(jié)了不足之處。項(xiàng)目已經(jīng)通過了驗(yàn)收,運(yùn)行良好,基本達(dá)到了預(yù)期目標(biāo)。
[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.
