With the capabilities of communication automation, office automation, and building equipment automation, as well as the most optimized combination of systematic structure, services and management, intelligent buildings provide people with a safe, comfortable and convenient building environment. Its intelligent is realized through the computer network, only when the information of all subsystems is transferred and interacted in time .The computer network is a computer system that combines mutiple computers and their periphral equipment in different positions with individual functions which linked by communication lines, under the management and coordination of network operating system, management software and communication protocols to realize resource sharing and information transfer.The intelligent building is the product of modern building technology and the emerging information technology,which improves the value and safety of the building itself as well as providing users with a comfortable and convenient environment through the optimal combination of a buildings structure, system, service and management.Based on the network construction of the Subtropical Agriculture Institute of Chinese Academy of Science, this paper studies the network design and implementation of intelligent buildings.Key words:intelligeng building；computer network；network opearting system；Chinese Academy of Science。目录1 概述11.1 智能楼宇技术概况11.2 智能楼宇网络技术概况22 需求分析32.1 研究院概况32.2 用户网络需求32.2.1 带宽性能需求32.2.2 稳定可靠需求32.2.3 网络安全需求42.2.4 应用服务需求42.3 网络主要技术需求43 局域网技术53.1 局域网的定义53.2 以太网技术53.2.1 以太网的应用53.2.2 以太网物理层63.2.3 以太网数据链路层83.2.4 以太网交换机84 VLAN技术134.1 VLAN技术概述134.2 VLAN优势134.3 VLAN类型144.4 VLAN发展趋势155 网络安全165.1 网络安全概述165.2 防火墙技
