Design of Campus Gateways and Certification System

针对校园网的特点,提出一种新的校园网的网关与认证模式。介绍系统的总统设计,具体描述了包括IP转发控制、身份认证、数据库、网关控制模块、流量控制等实现过程。该系统实现了对于用户身份的鉴别,同时保证了对于上层的协议和用户的透明性,用户与IP地址绑定,而且充分利用网络特性能够支持大型网络。系统具有通用、易扩展、灵活、安全、使用方便的特点。

Introduces a new campus network gateway and uthentication model. An overall design of this new model is fully described including the implementation of IP transmit control, identification anthentieation, database, gateway control module and flow control. This program can distinguish the user＇s identification and guarantee the pellucidity between the upper layer and the user. The user will be bound with the IP address and a large scale of network can be supported with the help of this program. This program is common, easy-expanding, flexible , security and convenient in use.
