【摘要】：隨著計算機技術的不斷發(fā)展,網(wǎng)絡逐漸成為人們生活不可分割的一部分。人們的日常生活日益與網(wǎng)絡息息相關,在這其中,各種各樣的網(wǎng)絡應用發(fā)揮著重要的作用。人們可以利用不同的網(wǎng)絡應用來滿足自身不同的需求：即時通信、資訊獲取、網(wǎng)絡求助、觀看視頻、企業(yè)洽談等等。與此同時,局域網(wǎng)絡也開始成為整個網(wǎng)絡中重要的一份子。不論是學校還是企業(yè),建設一個方便可用安全的網(wǎng)絡,用于滿足自己的特有需求已變得越來越普遍。但是,想要獲取安全的局域網(wǎng)絡也變得越來越復雜。越來越多的網(wǎng)絡應用的涌現(xiàn),不同的網(wǎng)絡硬件設備的安裝,以及網(wǎng)絡中本身就具有的病毒木馬等等,都會對整個局域網(wǎng)絡的管理造成困擾。因此,一個管理方便全面、可靠性高的局域網(wǎng)絡監(jiān)控管理系統(tǒng)變得越來越重要。 筆者所參與的商用監(jiān)控管理系統(tǒng)致力于解決這方面的問題。本文中,筆者對該系統(tǒng)的一些關鍵技術及模塊進行了研究,主要包括網(wǎng)絡監(jiān)控系統(tǒng)中,網(wǎng)絡流量監(jiān)測模塊的研究,以及監(jiān)控系統(tǒng)中拓撲發(fā)現(xiàn)方法的研究與改進。 本文首先介紹了該論文的研究背景和意義,然后對于當前局域網(wǎng)絡以及網(wǎng)絡監(jiān)控的情況進行了介紹。繼而在上述研究的基礎上,本文介紹了筆者所參與研發(fā)的商用局域網(wǎng)絡監(jiān)控管理系統(tǒng),主要介紹了該系統(tǒng)的作用和系統(tǒng)結構,以及系統(tǒng)所實現(xiàn)的功能。之后,文章在隨后的幾章中,探討了監(jiān)控管理系統(tǒng)中幾個模塊的研究。首先是對網(wǎng)絡流量識別檢測模塊的研究。該部分主要解釋了網(wǎng)絡流量檢測以及網(wǎng)絡應用識別的情況,并且針對不同的識別技術,舉出了對應的不同的網(wǎng)絡應用實例。在SNMP網(wǎng)絡拓撲管理模塊中,論文論述了SNMP技術,并介紹了以此為基礎,建立網(wǎng)絡拓撲的過程。隨后介紹了本文所提出的,基于STP和AFT的網(wǎng)絡拓撲發(fā)現(xiàn)方法,并指出了該新的算法的優(yōu)越性能。
[Abstract]:With the continuous development of computer technology, the network has gradually become an integral part of people's lives. People's daily life is increasingly closely related to the network, in which a variety of network applications play an important role. People can use different networks to meet their different needs: instant messaging, access to information, network help, watching video, business negotiations and so on. At the same time, LAN also began to become an important part of the whole network. It has become increasingly common for schools and businesses to build a convenient and secure network to meet their own unique needs. However, the local area network that wants to obtain security also becomes more and more complex. The emergence of more and more network applications, the installation of different network hardware devices, and the virus Trojan horse in the network will make trouble for the management of the whole LAN. Therefore, a local area network monitoring and management system with convenient and comprehensive management and high reliability becomes more and more important. I participate in the commercial monitoring and management system to solve this problem. In this paper, the author studies some key technologies and modules of the system, including the research of network monitoring system, network traffic monitoring module, and the research and improvement of topology discovery method in monitoring system. This paper first introduces the research background and significance of this paper, then introduces the current local area network and network monitoring situation. Then, on the basis of the above research, this paper introduces the commercial LAN monitoring and management system developed by the author, mainly introduces the function and structure of the system, as well as the functions of the system. Then, in the following chapters, the research of several modules in the monitoring and management system is discussed. First of all, the research of network traffic identification and detection module. This part mainly explains the situation of network traffic detection and network application identification, and lists different network application examples for different identification techniques. In the SNMP network topology management module, this paper discusses SNMP technology, and introduces the process of establishing network topology based on SNMP technology. Then, this paper introduces the proposed network topology discovery method based on STP and AFT, and points out the superior performance of the new algorithm.
