针对校园网准入控制流行方案中存在对硬件设备有依赖或对终端系统软件有较高要求的缺陷,提出使用隔离网段的方法来实现校园网准入控制及无感知的认证方式.首先从理论上论证该方案的可行性,然后编写改进后的DHCP(动态主机配置协议)服务器,配置相应的网络,对认证方式进行验证.系统实际测试表明:在有线网络和无线网络情况下,该方案均能实现有效的准入控制和无感知认证.
Aiming at the existing defects in the popular admission control scheme of campus network, such as the dependence on hardware devices or the high demand on the terminal system software, a method of using isolated network segments is proposed to realize admission control and non-aware authentication in campus network. The feasibility of this scheme is demonstrated in theory, and then an improved DHCP (Dynamic Host Configuration Protocol) server is prepared and the corresponding network is configured to verify the authentication method.The practical tests show that in wired network and wireless network, this scheme Can achieve effective admission control and non-perceived certification.
