高校校园网规划与设计
[摘要] 随着网络技术的发展和普及,高校校园网络的建设也面临着新的挑战,是高校向信息化发展的必然选择,高校校园网已经成为各高校发展的重要基础设施,是提高高校教学和发展水平不可缺少的支撑环境,也是衡量高校学术水平和管理水平的重要标志。各高校都在筹备建设校园网,希望通过校园网的建设,增加硬件的投入,改善办学条件,提高教学、科研和管理水平,提高办学质量。高校校园网的建设必须做到经济适用、技术先进、开放性能良好,投资强度合理、能长期和稳定运行的高性能的校园网络。现在大多数的校园网工程建设主要都是采用了以太网技术来建设和管理的,以太网支持的传输媒体从最初的同轴电缆发展到现今的双绞线和光缆,实现了以太网系统带宽的快速增长,因此本课题设计将介绍和实践高校以太网建设中可能采用的各种网络技术,为高校校园网的规划设计提供理论依据和实践指导。本文以广西XX高校为背景来规划与设计校园网方案。

University Campus Network Planning and Design
[Abstract] Along with the development of network technology and popularization, campus network construction faces new challenges, and it is the universities to informationization development inevitably choice. College campus has become an important infrastructure at each college development, and it is the indispensable support environment to improve the university teaching and the development level, and an important symbol of the measure university academic level and the level of management. Universities are preparing to build campus network, hope that through the construction of network, increase hardware input, improve managerial condition, improve teaching, scientific research and management level and improve teaching quality. The construction of campus network must accomplish economy applicable, advanced technology, good performance, open investment intensity reasonable, can the long-term and stable operation of high performance of campus network. Now most of the campus network project construction were mainly adopts Ethernet technology to construction and management, Ethernet supports transmission media from the initial coaxial cable to today's twisted-pair cable and optical fiber, realized the rapid growth of Ethernet system bandwidth, and this subject will be designed to introduce and practice various network technology which may be adopt in the construction of college Ethernet, and providing theoretical basis and practical guidance to the university campus planning design.
