摘 要
随着internet技术的快速进步，根据国家科教兴国的策略，众多的学校合并，联网，共享资源；使它们互连起来成为一个整体满足教学、科研、办公自动化和信息化建设的需求。结合实际及当前成熟的网络技术，我们规划设计了一个具有高可靠性和开放性的校园网络。本设计可以方便的将学校的各个办公室、计算机机房和网络设备连接起来、把各教学楼有机的连接起来，使校园内所有的计算机互相之间能进行访问，达到资源共享、适应新形式下基于INTERNET的远程教育需要。在这次设计中，我们使用了思科路由器交换机模拟器Packet Tracer 仿真模拟了中学校园网的规划设计并做设计方案。在设计中运用了NAT，DHCP，RIP，ACL，GRE-VPN，STP端口安全等网络技术，满足了学校对校园网的各种需求。
关键词：远程教育、办公自动化、地址转换NAT、DHCP

Abstract
With the rapid advancement of internet technology, according to the national strategy of rejuvenating the country, many of the school consolidation, networking, sharing of resources; make them interconnected as a whole to meet the needs of teaching, research, office automation and information construction. Combined with practical and current mature network technology, we plan to design a high reliability and openness of the campus network. This design can easily be each school's office, computer room and network devices connected together, the various school buildings organically linked, so that all the computers on campus can be accessed from each other, sharing resources, adapt to the new form based on INTERNET distance education needs. In this design, we used Cisco routers and switches simulator Packet Tracer simulation of the high school campus network planning and design and make design. Use of NAT, DHCP, RIP, ACL, GRE-VPN, STP port security and other networking technologies in the design to meet the various needs of the school campus network.
Keywords: distance education, office automation, address translation
NAT, DHCP
