校园网用户的认证管理通常采用代理服务器或者网关等形式,这是由于在校园网中基本都是采用LAN和WLAN方式完成用户接入,而通常情况下用户使用校园网内部资源不需要进行认证,而用户认证计费通常发生在校园网的出口位置,因此代理服务器和网关的形式比较容易实现。传统的认证管理方式存在着比较明显的弊端,例如代理服务器只能支持少量的协议, Campus network users usually use proxy server or gateway authentication management, which is due to the basic campus network using LAN and WLAN access to complete the user, and usually users of the campus network resources do not need to be certified, The user authentication and accounting usually occurs in the campus network exit location, so proxy server and gateway form easier to achieve.
