【摘要】：計(jì)算機(jī)網(wǎng)絡(luò)發(fā)展的速度相當(dāng)迅速,所以人們對(duì)網(wǎng)絡(luò)管理方面的需求也就越來(lái)越大。在這種環(huán)境下,SNMP即簡(jiǎn)單網(wǎng)絡(luò)管理協(xié)議得到了廣泛應(yīng)用。SNMP與其他管理協(xié)議相比,突出的特點(diǎn)是簡(jiǎn)單。在Windows中,有一套應(yīng)用程序接口WinSNMP,是專門(mén)用于開(kāi)發(fā)基于SNMP協(xié)議的應(yīng)用的。本監(jiān)控系統(tǒng)就是基于WinSNMP,并使用開(kāi)發(fā)包SNMP++,結(jié)合網(wǎng)絡(luò)實(shí)驗(yàn)環(huán)境而開(kāi)發(fā)的網(wǎng)絡(luò)監(jiān)控系統(tǒng)。本文從網(wǎng)絡(luò)管理的功能和定義開(kāi)始分析,闡述了SNMP的基本管理模型和MIB管理信息庫(kù)結(jié)構(gòu),并著重解析了SNMP協(xié)議的工作方法。依據(jù)基于SNMP協(xié)議進(jìn)行網(wǎng)絡(luò)管理的特點(diǎn),設(shè)計(jì)并實(shí)現(xiàn)了具有四大功能模塊的網(wǎng)絡(luò)監(jiān)控系統(tǒng)。在詳細(xì)論述了基于WinSNMP和SNMP++獲取網(wǎng)絡(luò)設(shè)備相關(guān)數(shù)據(jù)的途徑和介紹了SNMP++開(kāi)發(fā)包在系統(tǒng)開(kāi)發(fā)中能提供便利的功能函數(shù)后,實(shí)現(xiàn)了利用樹(shù)圖瀏覽代理的MIB對(duì)象;監(jiān)控網(wǎng)絡(luò)設(shè)備;發(fā)現(xiàn)網(wǎng)絡(luò)拓?fù)浜吞幚砉收舷⒌确矫娴膬?nèi)容。其中瀏覽MIB對(duì)象模塊可以獲取代理機(jī)器的基本信息,監(jiān)控模塊是本系統(tǒng)的重點(diǎn),可以查找某一網(wǎng)段中所有支持SNMP協(xié)議的設(shè)備,并以列表的形式表現(xiàn)出來(lái),在選定了某一被管設(shè)備后,可以查看其各項(xiàng)有關(guān)數(shù)據(jù),如內(nèi)存大小,CPU負(fù)荷,開(kāi)放的接口等。除此之外還可以對(duì)選定的端口進(jìn)行流量監(jiān)控,以掌握當(dāng)前網(wǎng)絡(luò)的使用情況以供管理員分析和制訂相關(guān)策略。系統(tǒng)中的拓?fù)浒l(fā)現(xiàn)功能可以將當(dāng)前網(wǎng)絡(luò)中支持CDP協(xié)議的設(shè)備的拓?fù)鋱D繪制出來(lái),處理故障則是依靠SNMP協(xié)議中Trap消息的傳送來(lái)實(shí)現(xiàn)。本系統(tǒng)為網(wǎng)絡(luò)管理提供了一些方法,通過(guò)實(shí)際測(cè)試驗(yàn)證了相關(guān)功能的可行性。在文章的最后也提出了系統(tǒng)的不足之處和進(jìn)一步優(yōu)化的方向。
[Abstract]:With the rapid development of computer network, the demand for network management is increasing. In this environment, SNMP, the simple network management protocol, has been widely used. SNMP is compared with other management protocols. In Windows, there is a set of application program interface WinSNMP. it is used to develop the application based on SNMP protocol. This paper analyzes the function and definition of network management, expounds the basic management model of SNMP and the structure of MIB management information base. The working method of SNMP protocol is analyzed emphatically. According to the characteristics of network management based on SNMP protocol, This paper designs and implements a network monitoring system with four functional modules. After discussing the way of obtaining network equipment data based on WinSNMP and SNMP in detail and introducing the function function that SNMP development kit can provide in the system development. The MIB object of the proxy is realized by tree graph, the network device is monitored, the network topology is discovered and the fault message is processed. Among them, the browsing MIB object module can obtain the basic information of the proxy machine. Monitoring module is the focal point of this system. It can find all the devices in a network segment that support SNMP protocol, and display it in the form of list. After a certain managed device is selected, the relevant data can be viewed, such as the memory size and the load of SNMP. Open interfaces and so on. In addition to the selected port flow monitoring, In order to master the usage of the current network for administrators to analyze and formulate related policies. The topology discovery function in the system can draw the topology diagram of the devices supporting CDP protocol in the current network. The fault handling is realized by the transmission of Trap message in SNMP protocol. This system provides some methods for network management. The feasibility of the related functions is verified by practical tests. At the end of the paper, the shortcomings of the system and the direction of further optimization are also proposed.
