校园网毕业设计校园网络设计方案

摘要

随着计算机网络技术的发展，网络技术在给人们生活、工作的各方面带来方便和快捷，校园网络的建设已成为学校向信息化发展的必然选择。校园网网络系统是一个非常庞大而复杂的系统，它不仅为综合信息管理、现代化教学和办公自动化等一系列应用提供基本操作平台，而且能提供多种应用服务，使信息能及时、准确地传送给各个系统。从当今世界发达国家教育信息化发展的经验来看，从单机发展到网络，是中高校教育信息化发展的必然趋势。校园网建设势在必行。近年来我国高校校园网发展很快，潜力很大，但问题也很多。

校园网工程建设中主要应用了网络技术中的重要分支局域网技术,包括：VLAN，DHCP,DNS,WEB,FTP,SMTP等和计算机网络安全来建设与管理的。本毕业设计课题将主要以校园局域网络建设过程可能用到的各种技术及实施方案为设计方向，进行校园网总体设计，首先要进行对象研究和需求调查，明确学校的性质、任务和改革发展的特点及系统建设的需求和条件，对学校的信息化环境进行准确的描述；其次，在应用需求分析的基础上，确定学校Intranet服务类型，进而确定系统建设的具体目标，包括网络设施、站点设置、开发应用和管理等方面的目标；第三是确定网络拓扑结构和功能，根据应用需求建设目标和学校主要建筑分布特点，进行系统分析和设计；第四，确定技术设计的原则要求，如在技术选型、布线设计、设备选择、软件配置等方面的标准和要求；第五，规划校园网建设的实施步骤。以此为校园网的建设提供理论依据和实践指导，建设一个完整统一、技术先进、高效稳定、安全可靠、易于管理的基于Internet/Intranet的信息化校园网系统。

Abstract

With the development of computer network technology, networking technology in people's lives, working convenience and shortcut, the construction of campus network has become the inevitable choice of schools to the information development. Campus network system is a very large and complex system, not just for comprehensive modernization of information management, teaching, and provides basic office automation applications and a series of platforms, and can provide a wide range of application services, make information timely and accurately transferred to the various systems. From the experience of educational Informationization development in developed countries in the world today, from stand-alone to the development of networks, is an inevitable trend of development of higher education informatization in. The construction of campus network is imperative. Campus network developed rapidly in recent years, has a great potential, but also a lot.

Main application of network technology in campus network construction in the important branch of local area network technology, including: VLAN,DHCP,DNS,WEB,FTP,SMTP, and to construction and management of computer network security. This graduated design topics will main to campus Council domain network construction process may with to of various technology and the implementation programme for design direction, for campus network overall design, first to for object research and demand investigation, clear School of nature, and task and reform development of features and the system construction of demand and conditions, on school of information environment for accurate of description; second, in application demand analysis of Foundation Shang, determine school Intranet service type, turn determine system construction of specific target, including network

facilities, and site set, and development application and management, aspects of target; third is determine network topology structure and function, under application demand construction target and school main building distribution features, for system analysis and design; IV, determine technology design of principles requirements, as in technology selection, and wiring design, and device select, and software configuration, aspects of standard and requirements; v, planning campus network construction of implementation steps. This is campus network construction of theory basis and practice provide guidance, building a full uniform, advanced technology, efficient, stable, safe and reliable, easy to manage information system in campus network based on Internet/Intranet.
