【正文】 快的發(fā)展態(tài)勢。 我國的網(wǎng)絡模擬實驗系統(tǒng)的研究起步較晚，但是發(fā)展速度較快。作為培 養(yǎng)和提高學生動手實踐能力、觀察能力、分析問題和解決問題能力等方面有著先天優(yōu)勢的實驗教學是高校教育改革的關鍵問題之一。 III Network simulation system Design and Realization Author： Liu Tongquan Tutor： Chen Jianhui Abstract This paper describes using the Cisco Packet Tracer software platform designing and implementing a work of a small or medium pany .It can realize the munication between departments, head office and branch office, the panies and the Inter ,and achieve the exchange between individuals and panies. It relates to work security, data encryption, and other related work issues in the process of designing the work. It applicate of virtual local area work protocols, work address translation, dynamic host settings, point to point protocol, frame relay, virtual private works, open shortest path first protocol and other related working technologies and protocols. In the process of writing this paper, it aims to bining theory and practical application. It expounds the theory with some instructions of practical applications and operating skills. And I hope it can fully reflect the knowledge and technology in the application and implementation of this system.

I 網(wǎng)絡模擬實驗系統(tǒng)的設計實現(xiàn) 摘 要 本文介紹了使用 Cisco 公司的 Packet Tracer 軟件模擬網(wǎng)絡實驗系統(tǒng)平臺，設計并實現(xiàn)了一個中小型公司內部各部門之間、總公司與分公司之間、公司與互聯(lián)網(wǎng)以及出差在外的個人與公司之間信息交流的互聯(lián)網(wǎng)絡，其間網(wǎng)絡的配置涉及到網(wǎng)絡的安全、數(shù)據(jù)的加密等相關網(wǎng)絡技術問題。 ? ? II 關鍵詞 網(wǎng)絡模擬平臺；網(wǎng)絡；實驗；信息 創(chuàng)新點 本文的創(chuàng)新點在于運用網(wǎng)絡模擬軟件十分真實地模擬出了網(wǎng)絡工程項目設計的全部流程，并以網(wǎng)絡實驗項目的實現(xiàn)為平臺來展示網(wǎng)絡模擬系統(tǒng)的功能。 experimentation Innovation The innovation of this paper is that use virtual work platform quite vividly simulating all of the engineering project designing process of a work. It shows the strong function of work simulation system by realizing the work experimental projects as a platform .
