隨著中小型企業(yè)的高速發(fā)展，對網(wǎng)絡(luò)處理和傳輸性能提出了新的要求。由于網(wǎng)點接入路由器和終端接入設(shè)備年代較久，性能和擴展能力都出現(xiàn)了瓶頸，嚴(yán)重影響網(wǎng)點業(yè)務(wù)的發(fā)展和客戶服務(wù)質(zhì)量。為此本論文設(shè)計了一個中小型企業(yè)的網(wǎng)絡(luò)工程，從而解決了由于設(shè)備性能低下出現(xiàn)瓶頸的問題，而且提高了企業(yè)網(wǎng)絡(luò)工程的擴展能力。 本論文首先討論了中小企業(yè)網(wǎng)的背景、意義、應(yīng)用現(xiàn)狀以及研究與開發(fā)現(xiàn)狀，然后對OSPF協(xié)議、DHCP協(xié)議、VLAN的劃分、靜態(tài)路由以及數(shù)據(jù)流控制等相關(guān)技術(shù)理論作了簡單的論述，其次結(jié)合工程項目，論述了企業(yè)網(wǎng)絡(luò)的需求分析、整體設(shè)計，其中包括對IP地質(zhì)的劃分，網(wǎng)絡(luò)拓?fù)鋱D等做了分析和描述。接下來，論文著重討論了基于OSPF協(xié)議的網(wǎng)絡(luò)工程的設(shè)計和實現(xiàn)，詳細(xì)地論述了各個協(xié)議的運用和實現(xiàn)方法。最后，對整個網(wǎng)絡(luò)進(jìn)行了測試。 關(guān)鍵詞：網(wǎng)絡(luò)工程；協(xié)議；性能；擴展 ABSTRACT With the rapid development of small and medium enterprises, this network processing and network transmission performance and scalability of terminal smooth raised new demands. As the network access routers and terminal access device's longer, performance and scalability bottlenecks have appeared, it affect the network business development and customer service. To this end this paper, an application of existing small and medium enterprises in network engineering, to solve the poor performance bottleneck because the equipment problems, and improve the ability of the corporate network expansion project. This paper first discusses the background of small and medium networks, meaning, application status, and research and development status, Then on the OSPF protocol, DHCP protocol, VLAN classification, static routing and data flow control and other related technology theory briefly discussed, Secondly, combined with the project, specifically addressing the needs of the corporate network analysis, overall design, including the division of IP addresses, network topology maps were analyzed and described. Next, the paper focused on the OSPF protocol-based network engineering design and implementation. Discussed in detail in the paper the use of various agreements and implementation methods. Finally, test the entire network. Keywords: Network engineering; protocol; performance; expansion
