23、多種服務(wù)和應(yīng)用。校園網(wǎng)的建設(shè)豐富了學(xué)習(xí)資源、提高了教育效率。但隨著用戶數(shù)的急劇增加和業(yè)務(wù)樣式的增多，校園網(wǎng)的安全問題也日益突出，無時(shí)無刻不在威脅校園網(wǎng)絡(luò)的健康發(fā)展，成為教育信息化建設(shè)中不容忽視的問題。本文著重論述了校園網(wǎng)設(shè)計(jì)與建設(shè)過程中確立建設(shè)校園網(wǎng)的目標(biāo)，校園網(wǎng)的技術(shù)方案設(shè)計(jì)，信息資源建設(shè)，應(yīng)用軟件的開發(fā)，網(wǎng)絡(luò)管理與安全五個(gè)關(guān)鍵問題。校園網(wǎng)絡(luò)作為學(xué)校重要的基礎(chǔ)設(shè)施，擔(dān)當(dāng)著學(xué)校教學(xué)、科研、管理和對(duì)外交流等許多角色。 </p>
