| 摘要：随着科学技术的发展，许多企业内部信息都依托网络传播。是否稳定畅通是评价企业网络的一个重要指标。本设计以塔塔信息技术（中国）股份有限公司为模型设计了一个网络拓扑。设计思路以如何保证网络的稳定性展开讨论，设计了一套具有网络备份的网络拓扑结构，在主设备停止工作时衔接网络数据的传输，既保证用户不会因为网络断开而丢失数据，同时又确保停止的设备文护好后也能并行工作。为确保主设备出现故障后冗余设备能及时接替主设备的工作，采用了交换相互冗余备份和防火墙失效转移的方法。而采用的技术是HSRP热备份路由协议和Failover失效转移，同时在交换机端口上限制Mac地址策略实现规范用网。在本次课程设计当中用的最多的是交换机，一个公司里主要是以内部数据交换较为量大，主要的是核心交换机的冗余备份，同时规范公司用网制度，确保除工作Pc外没有其他外接网络，本次课程设计也是充分体现个人动手能力的方式。5544 关键词：交换机；防火墙；冗余备份；失效转移 Design of Enterprise LAN Abstract: In modern society, lots of information needs the support of network communication with the development of science and technology. But in the network era of rampant, to ensure the smooth network is a very important task. So this design is mainly focusing on how to ensure the stable network is discussed, taking TATA information technology (China) Limited by Share Ltd as a model. The design of network to ensure the smooth need backup of a network interface device, the network data transmission in the main equipment stops working, not only to ensure that the user will not lose data because of the disconnection of the network, but also ensure that can work in parallel to stop the equipment maintenance. The method of exchange redundancy and the failure of firewall transfer, but the technology is HSRP hot standby routing protocol and Failover failover, while limiting the address of the Mac strategy to achieve the specification for network in the switch port. In the course of design with the largest number of switches, a company is mainly by the internal data exchange is large, it is redundant backup core switch.At the same time specification for network system of the company is important. To ensure that no other external clients have access to network in addition to worker`s Pc.The curriculum design is also fully embodies the personal ability way.
