【摘要】：計算機網絡發(fā)展的速度相當迅速,所以人們對網絡管理方面的需求也就越來越大。在這種環(huán)境下,SNMP即簡單網絡管理協(xié)議得到了廣泛應用。SNMP與其他管理協(xié)議相比,突出的特點是簡單。在Windows中,有一套應用程序接口WinSNMP,是專門用于開發(fā)基于SNMP協(xié)議的應用的。本監(jiān)控系統(tǒng)就是基于WinSNMP,并使用開發(fā)包SNMP++,結合網絡實驗環(huán)境而開發(fā)的網絡監(jiān)控系統(tǒng)。本文從網絡管理的功能和定義開始分析,闡述了SNMP的基本管理模型和MIB管理信息庫結構,并著重解析了SNMP協(xié)議的工作方法。依據基于SNMP協(xié)議進行網絡管理的特點,設計并實現了具有四大功能模塊的網絡監(jiān)控系統(tǒng)。在詳細論述了基于WinSNMP和SNMP++獲取網絡設備相關數據的途徑和介紹了SNMP++開發(fā)包在系統(tǒng)開發(fā)中能提供便利的功能函數后,實現了利用樹圖瀏覽代理的MIB對象;監(jiān)控網絡設備;發(fā)現網絡拓撲和處理故障消息等方面的內容。其中瀏覽MIB對象模塊可以獲取代理機器的基本信息,監(jiān)控模塊是本系統(tǒng)的重點,可以查找某一網段中所有支持SNMP協(xié)議的設備,并以列表的形式表現出來,在選定了某一被管設備后,可以查看其各項有關數據,如內存大小,CPU負荷,開放的接口等。除此之外還可以對選定的端口進行流量監(jiān)控,以掌握當前網絡的使用情況以供管理員分析和制訂相關策略。系統(tǒng)中的拓撲發(fā)現功能可以將當前網絡中支持CDP協(xié)議的設備的拓撲圖繪制出來,處理故障則是依靠SNMP協(xié)議中Trap消息的傳送來實現。本系統(tǒng)為網絡管理提供了一些方法,通過實際測試驗證了相關功能的可行性。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.
