校园局域网整体解决方案设计

摘要：校园网是当今信息社会发展的必然趋势。它是建立在现代网络技术、多媒体技术和因特网技术的网络，一方面可以连接校园内的所有终端设备，另一方面是连接校园内外网络的媒介。本文针对高校实际需求，设计出一套高速，安全，能实现各个分区和中心之间的连接，以及到互联网访问的校园网方案。根据调研，本设计基于实际信息点需求，采用思科三层模型来进行整体规划，设计合理的网络拓扑，对接入层，汇聚层和核心层进行了基础配置与说明，在互联网接入区设置安全策略，并采用了NAT，ACL，STP，链路聚合等核心技术，最后本文对校园网内外网两个方面进行安全分析，从OSI七层模型，无线局域网等方面实现了校园网的安全部署，满足了对资源保护的要求，提高了校园网整体安全性。62055

The Overall Solution Design of Campus Local Area Network

Abstract: Campus network is the inevitable trend of development of information society. It is a modern network of computer network technology, multimedia technology and Internet technology as the foundation established, on the one hand connected subnets within the school campus and dispersed throughout the terminal, on the other hand as a communication bridge between the external network on campus. In this paper, the actual needs of colleges and universities, to design a high-speed, secure, able to connect the various partitions and centers, as well as access to the Internet campus network program. According to research, the design based on actual demand information points using Cisco three-layer model for the overall planning, rational design of the network topology, the access, aggregation and core layers were basic configurations and instructions for setting up Internet access in the region security policy, and the use of NAT, ACL, STP, link aggregation and other core technology, campus network Finally, two aspects of internal and external network security analysis, from the OSI model, wireless LAN, etc. to achieve a safe campus network deployment meet the requirements for resource protection and improve the overall safety of the campus network.

Keywords: Campus network layer model; wireless LAN; network security; switches; router
