【摘要】：基于LWAPP協(xié)議的多AP模擬工具的設(shè)計(jì)和實(shí)現(xiàn)主要用來解決無線控制器測試過程中出現(xiàn)的多無線接入點(diǎn)和多用戶終端接入測試?yán)щy的問題。多AP模擬工具模擬真實(shí)AP的通信過程,實(shí)現(xiàn)大規(guī)模AP接入,AC集中管理,模擬現(xiàn)實(shí)場景中的的企業(yè)網(wǎng)絡(luò)部署。通過這種方法,來驗(yàn)證無線控制器產(chǎn)品本身的承壓能力和接入處理性能。實(shí)現(xiàn)WIPS功能的多AP模擬工具,在基本AP的基礎(chǔ)上添加了AP的另外一種身份,即網(wǎng)絡(luò)監(jiān)測器sensor,來實(shí)時(shí)監(jiān)測網(wǎng)絡(luò)中的通信情況。實(shí)現(xiàn)了無線入侵防護(hù)功能的多AP模擬工具,可以驗(yàn)證無線控制器的WIPS模塊的工作情況,更可以用來驗(yàn)證WIPS系統(tǒng)在大規(guī)模sensor(開啟了WIPS功能的AP)部署下的穩(wěn)定性,不同無線環(huán)境下的sensor的部署規(guī)模及其推薦的默認(rèn)值等大規(guī)模應(yīng)用問題。本文主要著力于多AP模擬工具的開發(fā),尤其是無線入侵防護(hù)系統(tǒng)的開發(fā)。首先,講述了WLAN相關(guān)知識,有助于對WLAN網(wǎng)絡(luò)進(jìn)行充分的了解,并分析LWAPP網(wǎng)絡(luò)架構(gòu);接下來,對無線入侵防護(hù)系統(tǒng)進(jìn)行了詳細(xì)的闡述,深刻理解WIPS系統(tǒng)各功能實(shí)現(xiàn)原理及工作機(jī)制;隨后對整個(gè)軟件需求進(jìn)行了分析,設(shè)計(jì)軟件架構(gòu)。根據(jù)模擬工具應(yīng)用的場景,最終采用用戶配置界面與工具獨(dú)立運(yùn)行的方案。最后對模擬工具進(jìn)行了系統(tǒng)測試,驗(yàn)證該工具的整體性能。整個(gè)工具分為多個(gè)模塊:AP模塊、STA處理模塊、報(bào)文模塊、統(tǒng)計(jì)模塊和日志模塊。AP模塊主要負(fù)責(zé)AP接入、認(rèn)證、關(guān)聯(lián),STA接入等一系列過程的處理。采用多線程實(shí)現(xiàn)多AP多STA接入無線網(wǎng)絡(luò)。報(bào)文模塊分別采用WinPcap/Socket對報(bào)文進(jìn)行收發(fā)處理,自行根據(jù)報(bào)文結(jié)構(gòu)封裝LWAPP報(bào)文。統(tǒng)計(jì)模塊主要是實(shí)時(shí)監(jiān)測網(wǎng)絡(luò)數(shù)據(jù)并輸出。日志模塊記錄網(wǎng)絡(luò)中發(fā)生的事件。在完成基本功能之后,對模擬工具進(jìn)行了性能驗(yàn)證,以達(dá)到穩(wěn)定高性能的運(yùn)行,來達(dá)到測試無線控制器的功能。軟件通過多方位測試,修改后,最終可以在Windows/Linux跨平臺穩(wěn)定運(yùn)行,既可以在本地運(yùn)行,也可以在服務(wù)器端運(yùn)行。根據(jù)主機(jī)的硬件性能的不同,可以對多款A(yù)C產(chǎn)品進(jìn)行壓力測試和性能測試。根據(jù)測試所獲取的數(shù)據(jù),可以采用相應(yīng)的WIPS系統(tǒng)網(wǎng)絡(luò)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.
