1、論 文 評 定指 導(dǎo) 教 師 意 見：指導(dǎo)教師：___________（簽中小型企業(yè)園區(qū)網(wǎng)的設(shè)計(jì)與實(shí)現(xiàn)—縣供電局辦公網(wǎng)建設(shè)第 3 頁 共 42 頁論文提要 論文提要中小型企業(yè)園區(qū)網(wǎng)是局域網(wǎng)中的一個(gè)特例，是實(shí)際網(wǎng)絡(luò)應(yīng)用中的一個(gè)重要網(wǎng)絡(luò)模型。目前，我國的電力信息化網(wǎng)絡(luò)已經(jīng)比較成熟，一個(gè)縣供電局與其下轄的供電所和變電站的企業(yè)網(wǎng)就是一個(gè)典型的中小型企業(yè)園區(qū)網(wǎng)?？h供電局園區(qū)網(wǎng)由三個(gè)部分組成：縣供電局大樓辦公網(wǎng)、供電所辦公網(wǎng)

2、和變電站辦公網(wǎng)?？h供電局園區(qū)網(wǎng)通常由 500-1000 臺計(jì)算機(jī)和服務(wù)器組成，為了減少網(wǎng)絡(luò)故障，簡化網(wǎng)絡(luò)管理，必須為其規(guī)劃 VLAN 及各 VLAN 使用的 IP 地址，通過 VLAN 技術(shù)將整個(gè)園區(qū)網(wǎng)絡(luò)在邏輯上劃分為更多的子網(wǎng)。設(shè)計(jì)供電局園區(qū)網(wǎng)還必須考慮到網(wǎng)絡(luò)核心層和接入層的承載能力，選用性能合適的硬件以保證整個(gè)網(wǎng)絡(luò)的帶寬足以滿足現(xiàn)有的和未來幾年的信息業(yè)務(wù)流量的要求。關(guān)鍵詞：園區(qū)網(wǎng)，縣供電局，VLAN，帶寬Small and medi
