【摘要】：基于LWAPP协议的多AP模拟工具的设计和实现主要用来解决无线控制器测试过程中出现的多无线接入点和多用户终端接入测试困难的问题。多AP模拟工具模拟真实AP的通信过程,实现大规模AP接入,AC集中管理,模拟现实场景中的的企业网络部署。通过这种方法,来验证无线控制器产品本身的承压能力和接入处理性能。实现WIPS功能的多AP模拟工具,在基本AP的基础上添加了AP的另外一种身份,即网络监测器sensor,来实时监测网络中的通信情况。实现了无线入侵防护功能的多AP模拟工具,可以验证无线控制器的WIPS模块的工作情况,更可以用来验证WIPS系统在大规模sensor(开启了WIPS功能的AP)部署下的稳定性,不同无线环境下的sensor的部署规模及其推荐的默认值等大规模应用问题。本文主要着力于多AP模拟工具的开发,尤其是无线入侵防护系统的开发。首先,讲述了WLAN相关知识,有助于对WLAN网络进行充分的了解,并分析LWAPP网络架构;接下来,对无线入侵防护系统进行了详细的阐述,深刻理解WIPS系统各功能实现原理及工作机制;随后对整个软件需求进行了分析,设计软件架构。根据模拟工具应用的场景,最终采用用户配置界面与工具独立运行的方案。最后对模拟工具进行了系统测试,验证该工具的整体性能。整个工具分为多个模块:AP模块、STA处理模块、报文模块、统计模块和日志模块。AP模块主要负责AP接入、认证、关联,STA接入等一系列过程的处理。采用多线程实现多AP多STA接入无线网络。报文模块分别采用WinPcap/Socket对报文进行收发处理,自行根据报文结构封装LWAPP报文。统计模块主要是实时监测网络数据并输出。日志模块记录网络中发生的事件。在完成基本功能之后,对模拟工具进行了性能验证,以达到稳定高性能的运行,来达到测试无线控制器的功能。软件通过多方位测试,修改后,最终可以在Windows/Linux跨平台稳定运行,既可以在本地运行,也可以在服务器端运行。根据主机的硬件性能的不同,可以对多款AC产品进行压力测试和性能测试。根据测试所获取的数据,可以采用相应的WIPS系统网络部署。
[Abstract]:The design and implementation of multi-AP simulation tool based on LWAPP protocol is mainly used to solve the problem of multi-wireless access point and multi-user terminal access test. Multi-AP simulation tool simulates the communication process of real AP, realizes large-scale AP access to AC centralized management, and simulates the enterprise network deployment in the real world. This method is used to verify the bearing capacity and access processing performance of the wireless controller product itself. Based on the basic AP, the multi-AP simulation tool which realizes the function of WIPS adds another AP identity, the network monitor sensor, to monitor the communication in the network in real time. A multi-AP simulation tool for wireless intrusion protection is implemented, which can verify the work of the WIPS module of the wireless controller, and can be used to verify the stability of the WIPS system under the large-scale sensor (AP with WIPS function turned on) deployment. The scale of sensor deployment and its recommended default values in different wireless environments are problems in large scale applications. This paper focuses on the development of multi-AP simulation tools, especially the development of wireless intrusion protection system. First of all, the related knowledge of WLAN is described, which is helpful to fully understand the WLAN network and analyze the LWAPP network architecture. Then, the wireless intrusion protection system is described in detail. The realization principle and working mechanism of each function of WIPS system are deeply understood, and then the whole software requirement is analyzed and the software architecture is designed. According to the scenario of simulation tool application, the user configuration interface and the tool run independently. Finally, the system test of the simulation tool is carried out to verify the overall performance of the tool. The whole tool is divided into several modules: AP module: STA module, message module, statistics module and log module. AP module is mainly responsible for AP access, authentication, associated STA access and a series of processes. Multi-AP multi-STA access wireless network is realized by multi-thread. The packet module uses WinPcap/Socket to send and receive the message, and encapsulates the LWAPP message according to the message structure. The statistical module mainly monitors and outputs the network data in real time. The logging module logs events that occur on the network. After completing the basic function, the performance of the simulation tool is verified to achieve a stable and high performance operation, to achieve the function of testing the wireless controller. After multidirectional testing, the software can run stably across the Windows/Linux platform, either locally or on the server side. According to the hardware performance of the host, many AC products can be tested under pressure and performance. According to the data obtained from the test, the corresponding WIPS system network deployment can be adopted.
