【摘要】 随着Internet和电子商务的发展,信息技术的应用模式发生了很大的变化,新技术的应用带来了多种多样的网络连接方式,网络的规模也越来越大。如何对网络中的各种资源进行有效的管理和分配,已经成为高校校园网络管理者的一个重要课题。 校园网络所面对的用户对象基本上是教师和学生两种类型,而学生用户占的比重要大很多。学生的创造性和破坏性是显而异见的,校园网络的管理者在网络出现问题后需要查找根源,而大多的问题都是人为的,因而对网络用户的管理是至关重要的。 本论文针对目前在校园网络管理中普遍存在的IP地址盜用和线路盜用,以及校园网络计费的问题,提出了一个现实有效的解决方案。该方案很好地解决了网络IP地址地动态分配,防止IP地址盗用和线路盗用,网络计费等当前校园网络管理中的典型问题。我采用基于802.1x协议及RADIUS协议的用户认证的技术来实现上述方案,通过IP地址、MAC地址、用户接入端口及用户帐号名的多重绑定来达到管理与控制的目的。此方案将在我校的校园网上运用。 该系统使用简单,具有安全性强、成本低等特点。在系统管理方面采用了B/S(Brower/Server)结构来实现用户、用户组及计费的管理,在系统认证方面采用了C/S(Client/Server)结构来实现用户的认证,基本达到网络用户管理,用户认证,IP、MAC地址的管理与控制,网络计费等功能,有效地提高了校园网络的管理效率。 通过本课题的研究和实现,可以使到校园网络的管理进一步完善,并大大地提高了校园网的网络性能,能够更好地为用户提供服务,有助于加快学校信息化建设的步伐。更多还原

【Abstract】 With the development of Internet and E-commerce, the applied model of Information Technology has been changed, the application of new technology take many kinds of network connections style and the increasing scale. How to manage and configure the varied network resources effectively has become a major project to many collegial network managers.Users of Campus Networks always are teachers and students. Student’s creation is huge, and sometimes full of destroy. So when a problem occur, manager of networks need to find out what had happened or who had done the attacts. Obviously, it is important to manage and control the networks users.In this paper, the system solving the problems for IP address, device management and accounting in campus was developed. Moreover, the system was implemented by the technology based on 802. lx and RADIUS protocol. There are still many problems in the network management, such as auto distribute static IP address, manage the user line, the port of switch and user’s MAC address, the accounting of network online. Such problems can be resolved effectively by this system.The management of system is based on the Browser/Server model with PHP as the development tools, and it use the Client/Server model to authenticate the network user. The system applied 802.lx protocol and Remote Authentication Dial-In User Service (RADIUS) protocol to finish the management of the port of switch and user’s MAC address. It included system configuration, information importing, IP address distribution, port and line management, network online accounting.This system can finish the network user management, address management and control, accounting. A cost and time saving network managing technique is available by using this system.After researched and implemented in this project, it can make the management of networks more consummate, and improve the performance of Campus Networks更多还原
