【摘要】：隨著計算機網(wǎng)絡(luò)技術(shù)的發(fā)展,校園網(wǎng)絡(luò)的應(yīng)用需求迅速增長,隨著網(wǎng)絡(luò)節(jié)點的增加,校園網(wǎng)絡(luò)的結(jié)構(gòu)將變的更為復(fù)雜,同時對設(shè)備性能、鏈路帶寬提出更高要求。建設(shè)一個基于多業(yè)務(wù)、復(fù)雜的校園網(wǎng)絡(luò)系統(tǒng),需要一種有效的手段對校園網(wǎng)進行規(guī)劃、設(shè)計并實現(xiàn)。通過數(shù)學(xué)建模的方法過于復(fù)雜,根據(jù)以往經(jīng)驗進行規(guī)劃設(shè)計的方法不可靠,無法滿足日益增長的校園網(wǎng)絡(luò)需求,利用網(wǎng)絡(luò)仿真軟件來對校園網(wǎng)絡(luò)進行建模并仿真收集數(shù)據(jù)分析便成為必然的選擇。 本文通過講述校園網(wǎng)常見的網(wǎng)絡(luò)拓撲結(jié)構(gòu)以及常用的網(wǎng)絡(luò)設(shè)備、網(wǎng)絡(luò)傳輸介質(zhì)、網(wǎng)絡(luò)技術(shù)等的運行原理及物理特點,在對上訴內(nèi)容進行總結(jié)分析的基礎(chǔ)上,結(jié)合單位校園網(wǎng)的網(wǎng)絡(luò)拓撲結(jié)構(gòu),通過OPNET仿真軟件,對單位校園網(wǎng)的網(wǎng)絡(luò)結(jié)構(gòu)進行建模,在建模的基礎(chǔ)上通過模擬仿真校園網(wǎng)常見的網(wǎng)絡(luò)行為,對網(wǎng)絡(luò)中的關(guān)鍵參數(shù)進行收集、分析。同時針對原有網(wǎng)絡(luò)仿真模型,在此基礎(chǔ)上通過添加網(wǎng)絡(luò)結(jié)點、改變鏈路帶寬等影響網(wǎng)絡(luò)性能的參數(shù)進行設(shè)置并再次進行建模仿真分析,得出網(wǎng)絡(luò)性能參數(shù)對原有網(wǎng)絡(luò)性能的影響。最后通過結(jié)合改進后的校園網(wǎng)拓撲結(jié)構(gòu)模型,得出校園網(wǎng)升級方案的可行性。 本文可以為校園網(wǎng)的規(guī)劃設(shè)計提供客觀可靠的定量依據(jù),提高網(wǎng)絡(luò)設(shè)計的科學(xué)性,縮短網(wǎng)絡(luò)建設(shè)周期,降低校園網(wǎng)絡(luò)投資的風(fēng)險,因而也具有一定的工程應(yīng)用價值。最后,對本文進行了總結(jié),同時對未來的工作進行設(shè)想和展望。
[Abstract]:With the development of computer network technology, the application demand of campus network grows rapidly. With the increase of network nodes, the structure of campus network will become more complex, and the equipment performance and link bandwidth will be higher requirements. To build a complex campus network system based on multi-service, we need an effective means to plan, design and implement the campus network. The method of mathematical modeling is too complex, the method of planning and designing based on previous experience is not reliable, and can not meet the increasing demand of campus network. It is an inevitable choice to use network simulation software to model campus network and collect data by simulation. This paper describes the common network topology of campus network, the common network equipment, network transmission media, network technology and other operating principles and physical characteristics, on the basis of summarizing and analyzing the appeal content. Combined with the network topology structure of the unit campus network, the network structure of the unit campus network is modeled by the OPNET simulation software. On the basis of the modeling, the key parameters in the network are collected by simulating the common network behavior of the campus network. Analysis At the same time, according to the original network simulation model, by adding network nodes, changing the link bandwidth and other parameters that affect the network performance, the modeling and simulation analysis is carried out again. The influence of network performance parameters on the original network performance is obtained. Finally, by combining the improved campus network topology model, the feasibility of campus network upgrade scheme is obtained. This paper can provide an objective and reliable quantitative basis for the planning and design of campus network, improve the scientific nature of network design, shorten the period of network construction and reduce the risk of campus network investment, so it has certain engineering application value. Finally, this paper is summarized, and the future work is envisaged and prospected.
