【摘要】：随着无线局域网(简称WLAN)技术的成熟,以及移动用户对网络带宽的需求快速增长,为了能够达到用户对带宽的需要,WLAN网络已被用做各大运营商的流量分流的工具。为了能够提供高质量的WLAN服务,使它可以高效的运行,开放、异构、跨平台的网络管理系统的开发将是未来的投入重点。本文主要对WLAN网络管理系统中设备数据监测分析系统进行了设计与开发。实现了WLAN网络中AP设备的获取、数据采集、运行监测等功能。实时监测设备数据、链路通断、服务运行的动态,对WLAN网络中设备的主要信息、设备和服务器运行信息、用户在线数和流量统计信息进行信息处理。该系统基于SNMP协议,根据逻辑视图分析并设计了系统结构,并完成了设备发现以及数据获取分析的功能,在本系统中,用户可以根据设定IP地址范围来发现网络中该地址范围内的AP设备,在此基础上依据SNMP协议以及MIB库的相关技术对这些设备的设备信息以及运行信息进行采集监测,利用柱状图、折线图以及表格等直观方式进行展示,从而系统有较好的可视性和易于管理性。本文主要从以下四个方面展开：首先,对项目的背景、意义、国内外研究现状进行了介绍,同时还对本文的主要工作以及组织结构进行了介绍。其次,对本文所使用的SNMP协议、SSH框架、三层体系结构以及JFreeChart技术等相关技术理论进行简单阐述。再次,对设备数据监测分析系统整体进行需求分析,并对系统各个子系统进行了划分,对各个子功能进行了需求分析,并依据各个功能对数据库设计进行了设计,并在数据库中添加各个表。最后,对WLAN网络设备性能数据监测分析系统进行了设计与实现。首先说明了设备性能数据监测分析系统的总体设计目标和总体架构设计,并对SNMP业务操作、网络监测配置、网络运行监测、性能统计与分析四个子系统进行了设计和代码实现。
[Abstract]:With the maturity of wireless local area network (WLAN) technology and the rapid growth of mobile users' demand for network bandwidth, In order to meet the needs of users for bandwidth, WLAN network has been used as a tool for traffic diversion of major operators. In order to provide high-quality WLAN services, it can run efficiently, open and heterogeneous. The development of cross-platform network management system will be the key input in the future. This paper mainly designs and develops the equipment data monitoring and analysis system in WLAN network management system, realizes the acquisition and data acquisition of AP devices in WLAN network. Functions such as real-time monitoring of equipment data, link break, dynamic operation of service, main information of equipment in WLAN network, operation information of equipment and server, The system is based on SNMP protocol, analyzes and designs the system structure according to logical view, and completes the functions of device discovery and data acquisition and analysis. The user can find the AP devices in the IP address range according to the IP address range. On this basis, according to the SNMP protocol and the related technology of MIB library, the device information and operation information of these devices can be collected and monitored. Using histogram, broken line diagram and table to display, so the system has better visibility and easy to manage. This paper mainly from the following four aspects: first, the background of the project, significance, The research status at home and abroad is introduced, and the main work and organization structure are also introduced. Secondly, the SNMP framework used in this paper is introduced. Third, the requirement analysis of the equipment data monitoring and analysis system as a whole, and the system sub-systems are divided, and the requirements of each sub-function are analyzed. According to each function, the database design is designed, and each table is added to the database. Finally, The design and implementation of WLAN network equipment performance data monitoring and analysis system are presented. Firstly, the overall design goal and architecture design of the equipment performance data monitoring and analysis system are described, and the SNMP service operation, network monitoring and configuration are also described. Four subsystems of network operation monitoring, performance statistics and analysis are designed and implemented.
