摘要
现有的无线局域网协议分析系统多采用基于PC的单点模式,操作人员需在现场实施分析,存在分析范围小、灵活性差等问题。该文提出一种分布式协议分析系统构架,该系统通过无线局域网数据采集设备对多个无线局域网采集数据,该设备与协议分析平台间通过CDMA2000网络多路数据链路进行远程控制和数据上传。给出了无线局域网协议分析的方法和数据采集设备的设计与实现,经测试表明该设备可以有效采集无线局域网通信信息,该系统能够准确地分析无线局域网协议,在安全防护、网络监测等方面有较好的应用价值。
Existing Wireless Local Area Network（WLAN） protocol analysis systems use mostly PC-based single-point mode. These systems have to be operated by the administrators on the spot. It can bring about many defects such as small range, less flexibility and so on. This paper presents a distributed multi-point analysis architecture, in which not only one WLAN is analyzed by placing several data collecting devices at the same time. Data collecting devices can be controlled remotely by the administrator via CDMA2000 network. The methods of analyzing WLAN protocol, the design and implementation of the data collecting device are also described in this paper. Test results prove that this device can collect WLAN communication information effectively. This system can be applied in many circumstances such as security protection and network monitoring.
