学院校园网规划方案

摘要

Internet的迅速发展，极推动了我国的网络建设。校园网的建设能从根本上促进教学科研人员之间的信息交流、资源共享、科研合作，是学校教育和科研工作的最重要的基础设施之一。本文通过介绍科技学院校园网的设计与建设,来说明高校在组建部网时所应经历的步骤；通过介绍该学校部网设计前的各种需求分析、设计方案的选择、网络安全维护工作以及最后的具体的组网实践，来说明如何高效安全地规划组建高校的校园网。

校园网的组建，是一个较先进且非常实用的课题，主要从校园网的需求和作用进行分析。校园网的建立，是多媒体教学的重要基础，首先教师可以多渠道、多方位、多形式的进行教学，可以把教程放在网上实现教学资源的共享，进行远程的教育、交流；另外学生可以更加广阔的学习知识并与老师有多种形式的交流。网络的无处不在让师生学习的空间和时间都得到了较大的延伸，可有选择性的主动学习、提高自身综合素质。使校园的办公管理进入一种高效、节约、严谨的状态，从而发生质的飞跃。校园网硬件系统的实施包括主干网、子网、服务器及各标准参数；软件系统包括网络通信协议、操件平台、应用软件、网络管理等。

Abstract

The rapid development of Internet has greatly promoted the construction of the network. Construction of the campus network from the fundamental teaching and research staff to promote the exchange of information between, resource sharing, research cooperation, is the school of education and research infrastructure of the most important one. This article introduces the Journal of Zhejiang University Campus Network Design and Construction, to illustrate the university intranet in the formation of the steps that should be experienced; by introducing the design of the pre-school intranet needs analysis, design choices, network security maintenance And, finally, the specific networking practice to illustrate how to build efficient and safe planning college campus network.

The set-up of campus network is a more advanced and very more practical subject, analyse from the demand and function for campus network mainly. Foundation , important foundation, multimedia of teaching, teacher can multi-channel diversified at first, a multi-form one carry on teaching, can put the study course on the net the sharing of realizing teaching resources , carry on long-range education , exchange; Study knowledge and having diversified forms of exchanges with the teacher that students can be wider in addition. Because the network is ubiquitous, the space and time of study get greater extension, alternative initiative study , improving one's own overall qualities. Make the office administration of the campus enter high-efficiently , economizes , rigorous, a real-time qualitative leap.

Implementation , hardware of system in the implementation , campus network, including backbone , sub network , server , all standard parameter; Implementation of software, including agreement under network , speak pieces of platform , application software , network

management.
