本文主要讲述了局域网络中信息交换过程中产生的安全问题,解决该问题的主要方法是三层交换技术,针对三层交换技术的实现原理和具体操作过程后,以现在高校的网络为主要分析对象,进行了三层交换技术的应用试验,并分析了研究的结果,根据实践的结果,初步拟定了校园三层网络的架构设计方案,结合了实际的软硬件情况,研究了设备的连接问题,IP的正确配置方法,通过正确的方法完成了三层交换技术的局域网信息安全构建。为以后更广的推行多层交换技术提供了前车之鉴,为局域网的信息交换,提供了更安全的方式。
This paper mainly describes the security issues in the process of information exchange in the local area network. The main method to solve this problem is the three-layer switching technology. According to the implementation principle and specific operation of the three-layer switching technology, Object, carried out the application of three-tier exchange technology test and analysis of the results of the study, based on the results of practice, initially proposed a three-tier campus network architecture design, combined with the actual situation of hardware and software, equipment connectivity problems , IP correct configuration method, through the correct method to complete the three-tier exchange of LAN information security technology. For the future more extensive implementation of multi-layer switching technology provides a warning for the local area network information exchange, providing a more secure way.
