Portal authentication method and system based on port

The invention discloses a Portal authentication method and system based on a port, and relates to the technical field of network communication. The method and the system solve the problem of repeatedauthentication when a Portal authentication technology and other authentication technologies coexist by isolating the Portal authentication technology from the authentication technologies of other modes. Meanwhile, according to the Portal authentication process, the user is temporarily allowed to have access to the network resource T1 for a long time, when the Internet surfing time of the user exceeds T1, Portal authentication is conducted on the user, frequent Portal authentication on the user is avoided, and the use experience is improved. 本发明公开了一种基于端口的Portal认证方法及系统，涉及网络通信技术领域，本发明通过将Portal认证技术与其他方式的认证技术进行隔离，避免Portal认证技术与其他认证技术共存时的多次认证问题；同时本发明的Portal认证流程，临时允许用户访问网络资源T1时长，当用户上网时长超过T1，则再对用户进行Portal认证，避免对用户进行频繁Portal认证，提高了使用体验。
