基于802.1x的校园网总体服务体系设计与实现

本文将改进的IEEE802.1x与CISCOSCE2000结合,设计实现了一整套的校园网用户接入控制、服务质量管理、网络应用管理、网络实时监控、网络计费,以及用户自助服务体系。有效地解决了目前大多数校园网中存在的地址盗用、网络带宽及应用难以管理等问题。同时,系统对IEEE802.1x的改进并没有改变其标准通讯机制和数据报文格式,因此可与所有厂商的交换机配合使用,避免了使用厂商私有客户端时受限于其设备的问题。

Design and realization of campus network service system based on IEEE 802.1x

In this paper, the implementation of a general-purpose campus network service system, which includes user access control, QoS management, network application management, network real-time monitoring, network billing system and user self-service system, is proposed. IEEE 802.1X is deployed for the system, and a CISCO SCE 2000 is introduced into the system. It can resolve the common problems exists in the most campus network, such as embezzling IP address, bandwidth and application management, and so on. 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 into the system.
