Study Of Campus Network Management System And Self-Service System

With the campus networks grow bigger and bigger, new network applications come forth faster than ever, the management of network become more difficult than few years ago. But the growing degree of informationization demand the network must have more security, availability, stability and scalability. Studies of new general-purpose network management pattern and user service model become the thing we must do.In this paper, the implementation of a general-purpose campus network management system, which includes user access control, quality of service management, network application management, network real-time monitoring, network billing system, and a user self-service system is proposed. IEEE 802.1x is deployed for the system, PPPoE and CISCO SCE 2000 is introduced into the system. An online payment system, which is compatible with many net bank and campus card, is implemented. It can be used by the self-service system and other systems in campus network. The normal communication mechanism and PDU format is not changed by our deployment, so the system can work with any vendor's Ethernet switches. The restriction that must work with specified switches when using some vendor's private 802.1x client is not introduced to the system.In this paper, the design proposal of the system is implemented, the key technology problems are resolved, and the adaptive 802.1x protocol and the authentication client are developed. The general-purpose campus network management system and user self-service system were tested; the online payment system is in use now. The study indicates that the systems in this paper can enhance the security, availability, stability and scalability of campus network.
