企业内部网络的设计与实现

摘 要随着社会的发展科技的进步，传统的传递信息的方式已经不能满足现代企业的需求。层出不同的中小型企业需要更加效率并安全的传递方式，本文以湖南长沙某中小型企业为背景，根据企业的需求和当代网络主流技术，设计一个能同时容纳 2000 人的的上网办公的网络方案。整个网络拓扑设计用经典的三层网络结构，在接入层用 VLAN 技术限制无用数据包的传输，对不同的部门进行隔离。在汇聚层使用双核心，防止小型网络错误造成整个网络无法通信，提高安全性，同时使用 VRRP 和 MSTP 技术进行数据的分流，合理的运用双核心资源。在核心层使用 OSPF，DHCP 中继使得不同部门能正常通信。关键词：中小型企业； 内部网； 路由； 交换；AbstractWith the development of science and technology in the development of society, the traditional way of transmitting information can not meet the needs of modern enterprises.Different small and medium-sized enterprises need more efficient and safe transmission methods. This paper takes a small and medium-sized enterprise in Changsha, Hunan Province as the background, according to the needs of the enterprise and the mainstream technology of contemporary network .Design a network scheme that can accommodate 2000 people at the same time. In the whole network topology design, the classical three-layer network structure is used. In the access layer, VLAN technology is used to restrict the transmission of useless data packets, and different departments are isolated. In the convergent layer, the dual-core is used to prevent the communication of the whole network caused by the small network error, and to improve the security. At the same time, the VRRP and MSTP technology are used to split the data, and the dual-core resources are used reasonably. The use of OSPFN DHCP relay at the core layer enables normal communication between different departments.Keywords: intranet; routing; switching;第一张 绪论1.1项目...
