摘要
近些年来,网络技术的发展速度已经到达了令世界瞠目结舌的地步,并且网络的发展越发的呈现出广泛化和深入化的特点。其中,在园区局域网的普及中最能体现这两点,在目前的社会环境中,想要参与到工作、学习中都离不开网络的支持,网络技术对于人类社会的巨大印象已经越来越成为一个世界性的课题。本文首先介绍了有关网络的一些基本概念知识,让读者对网络技术的框架有一个初步的了解,然后对园区局域网的现状及未来进行分析,进而讨论了在设计和实现园区局域网的规划时所要考虑的主要因素,最后给出了实现园区局域网的具体实现计划和操作规程,这一部分包括逻辑拓扑、物理拓扑的规划,虚拟局域网(Virtual Local work,VLAN)划分,IP地址规划以及小区局域网所具有的功能。
园区局域网是基于分层网络架构而设计的,实现了域名解析系统(Domain Name System,DNS)、动态主机配置协议(Dynamic Host Configuration Protocol,DHCP)、work Address Translation,NAT)等基本服务并启用认证授权记账(Authentication Authorization Accounting,AAA)服务。园区内部企业的远程用户可以通过虚拟专用网络(Virtual work,VPN)与园区内企业进行通信,资源。园区内部各VLAN之间通过动态路由协议连通。划分VLAN可以进行流量控制,并在一定程度上提高了网络传输的安全性,但为了维护VLAN信息的一致,各楼栋内接入交换设备采用VLAN中继协议(VLAN Trunking Protocol,VTP)。园区内还采用链路聚合技术增加网络冗余,以提高网络的稳定性和负载均衡;出于安全角度的考量,维护人员需通过安全外壳协议(Secure Shell,SSH)对园区设备进行远程管理维护。

ABSTRACT
In recent years, the pace of development work technology has reached the point where the world is staggering, and the development of work showing the more extensive and in-depth features. Among them, the best in the popularity of the campus LAN reflected in the current social environment, you want to participate in work and learning are inseparable from the support of work, network technology, a huge impression for the human society has e increasingly e a worldwide issue. This paper first introduces about work some of the basic concept of knowledge, so that the reader a preliminary understanding on the framework of work technology, then the status of campus LANs, and the future conduct analysis, and then discuss the design and to achieve campus LANs, and planning are to be consider Finally, a major factor, given the specific plans and operating procedures to achieve campus LAN, this part, including the planning of the logical topology, physical topology, virtual LAN (virtual Local work, VLANs) division, IP
