基于VLAN技术的某局域网改造方法

摘要

为解决某科研局域网常出现广播风暴、病毒传播、黑客入侵等问题,提出一种基于VLAN技术的具体改造方案.通过分析计算机网络的拓扑结构,采用以VLAN技术为基础,三层交换、访问控制、流量控制、入侵检测等技术手段进行补充改进.结果表明:改造后的局域网络在一定程度上减少了网络流量,节约了网络带宽,降低了网络内主机负载,使信息网络的快速高效和安全可靠性能大大提高.%For solving such network problems, like broadcast storms, viruses, hacking and even the virus spreading etc. This article presents a VLAN upgrading methods. By analyzing the topology of the computer network, use technology to VLAN-based, three-tier exchange, access control, flow control, intrusion detection and other technical means to complement improvements. The results show that after the transformation of the local area network to a certain extent, reduce network traffic and save network bandwidth and reduce network-host load, so fast and efficient, and the safety and reliability of information networks can greatly improve.
