校園網(wǎng)設(shè)計(jì)與RouterSim模擬

摘     要
 
 本文通過對校園網(wǎng)需求進(jìn)行分析，提出了一種以千兆以太網(wǎng)的星型連接為基礎(chǔ)，以高速千兆主干網(wǎng)為網(wǎng)絡(luò)系統(tǒng)核心，具有千兆主干，百兆到桌面的大型校園網(wǎng)解決方案。采用成熟可靠的技術(shù)為學(xué)校設(shè)計(jì)成一個(gè)技術(shù)先進(jìn)、簡單易用、性能優(yōu)秀、可升級擴(kuò)展的校園網(wǎng)絡(luò)。系統(tǒng)設(shè)計(jì)充分體現(xiàn)先進(jìn)性與實(shí)用性、系統(tǒng)與軟件可靠性、系統(tǒng)安全性與保密性、易管理與維護(hù)、易擴(kuò)充性等原則。本方案考慮到學(xué)校的中長期發(fā)展規(guī)劃，在網(wǎng)絡(luò)結(jié)構(gòu)、網(wǎng)絡(luò)應(yīng)用、網(wǎng)絡(luò)管理、，網(wǎng)絡(luò)安全等各個(gè)方面能夠適應(yīng)未來的發(fā)展，最大程度地保護(hù)學(xué)校的投資。校園網(wǎng)建設(shè)必然會(huì)對學(xué)校的信息化起到巨大的推動(dòng)作用，為學(xué)校的教學(xué)與辦公提供簡單、有效、便捷的理想環(huán)境。

Campus networks design and RouterSim’s simulation

Abstract
 Through much analysis towards the necessity of campus network, this paper aims to come up with a comprehensive campus network system. It bases on star-shaped connection of Gigabit Ethernet, taking backbone with high speed of Gigabit as its core. It owns huge campus network solutions of gigabit backbone and 100M desktop. what is more, the network boasts many advantages, including advanced technology, easy instructions, excellent performance and the possibility of upgrading and extending. The design of this system fully shows the advanced nature of system design and practicality, systems and software reliability, security and confidentiality, easy to manage and maintain the principles of easy expandability. In view of the medium and long-term developing plan of the schools, The program will be able to adapt to all aspects of future development and protect the investment of schools in the network structure, network applications, network management, network security mostly. Campus network construction will evidence promote the informationization of school ,which also provide the perfect condition of simpleness, availability and Convenience.

Keywords：Campus network; Ethernet; CISCO; Fireproofing wall
