Wireless hotspots have become popular, due to their ability to provide inexpensive and easy-to-deploy network infrastructures. Controlling and maintaining large-scale wireless infrastructures with traditional methods is complex and error-prone. Hence, it is necessary to use centralised solutions to handle configuration, monitoring and management functions in large-scale wireless hotspots. Existing solutions solve these problems within their hardware ecosystems and are constrained by vendor being depended on hardware and software restrictions. In this study, we propose and evaluate a wireless local area network (WLAN) access point (AP) controller built on top of a standard WLAN management protocol and free of any particular hardware and software restrictions. The proposed WLAN controller is a software component based on the control and provisioning of wireless access points (CAPWAPs) protocol. The proposed controller is evaluated by means of a TestBed including a variety of WiFi devices from different vendors to solve a QoS-LB problem.

基于软件的独立于供应商的WLAN控制器的开发

无线热点由于其提供廉价且易于部署的网络基础结构的能力而变得流行。用传统方法控制和维护大规模无线基础设施既复杂又容易出错。因此，有必要使用集中式解决方案来处理大规模无线热点中的配置，监视和管理功能。现有的解决方案在其硬件生态系统内解决了这些问题，并且受供应商所依赖的硬件和软件限制的约束。在这项研究中，我们提出并评估了建立在标准WLAN管理协议之上并且不受任何特定硬件和软件限制的无线局域网（WLAN）接入点（AP）控制器。所提出的WLAN控制器是基于无线接入点（CAPWAP）协议的控制和配置的软件组件。所提出的控制器是通过TestBed进行评估的，其中包括来自不同供应商的各种WiFi设备，以解决QoS-LB问题。
