【摘要】 无线局域网发展的势头越来越迅猛，它因为接入速率高、组网灵活，在传输移动数据方面尤其具有得天独厚的优势。然而，随着无线局域网应用领域的不断拓展，其管理和安全的问题也越来越受到人们的重视。由于无线局域网的特殊性，传统的局域网管理已经不能够覆盖，因此人们对无线网络管理提出了新的需求。一套有效的无线局域网管理系统，可以使无线局域网的性能最大化、安全性更强。本论文首先在引言部分介绍了发展背景以及国内外现状。介绍了无线局域网的基本组成结构和工作原理，然后讨论了无线IEEE802．11协议和IEEE802．1x认证技术。其次，又从简单网络管理协议入手，结合无线局域网分析其在无线网管管理中的重要作用。本文重点介绍了无线局域网管理系统中的主要内容和管理对象，以及安全管理方面的不同。在有线局域网网络管理系统的实现基础上，分析和研究了无线局域网领域中管理的新内容。分析了无线局域网当前存在的管理问题和安全问题，提出一套完整的无线局域网管理系统解决方案，分别提出了无线局域网接入点的集中管理配置方法、网络故障检测方法、安全检测方法、用户认证方法和计费方法、无线信道的带宽管理和无线网络的性能测量方法。此外，利用已形成的传统网管资源和无线网管相结合的技术，提出了无线局域网设备和终端的管理、位置和移动性的管理和其安全的管理的建议和方法。最后在本人参与的CNetMan网络管理系统的基础上，进行无线管理的部分设计和实现。更多还原

【Abstract】 Because of high access rate, flexible building, Wireless LAN has more and more rapid development and unique advantage of mobile data transmission. However, as the field of WLAN application is constantly expanding, its management and safety issues are attracting more attention. Due to the special characteristic of the WLAN, traditional LAN management could not involve all the management of WLAN, people put forward new demands. An effective WLAN management system can make WLAN performance better and safety stronger.The paper first introduces the background and development of WLAN at home and abroad. The paper tells about the basic structure and working principle of WLAN, and then discusses the wireless IEEE802.11 protocol and IEEE802.1x authentication techniques. Secondly, the paper starts from the SNMP, and analyzes the important role of WLAN management. The paper focuses on the main content, management targets in WLAN management system, as well as the different aspects of security management. Based on the realization of wired LAN management system, the paper analyzes and researches new content of WLAN management. Analysis of the existing wireless LAN management and security issues, the paper makes a complete WLAN management system solution, which include centralized configuration of WLAN access points, network trouble detection methods, security detection methods, user authentication and accounting methods, wireless channel band management and wireless network performance measurement. In addition, by integrating the technical and resources traditional of traditional network management with the wireless network management, the paper discusses the management of equipment and terminal management, location and mobility and security in WLAN. In the last part, the paper designs and implements some parts of the WLAN NMS base on the CNetMan NMS.更多还原
