在本文中，我们介绍了FoT的概念，这是一种按需物联网的范例。按需物联网是一个物联网平台，在这个平台上，可以根据实时需求通过统一的平台访问和管理异构的互联事物。由于物联网环境的大规模和复杂性，实现这样的平台面临着包括异构性、可扩展性、响应性和鲁棒性在内的挑战。FoT范式的特点是融合了雾计算能力，这不仅为物联网应用提供了支持，更重要的是对系统本身的可扩展和高效管理。FoT采用扁平结构的虚拟化平面和分层控制平面，这两个平面都延伸到网络边缘，并且可以真实的实时重新配置，以实现各种设计目标。除了描述FoT范例的详细设计外，我们还强调了这种按需物联网平台的部署，管理和运营所涉及的挑战和机遇。我们希望这篇文章能够阐明如何构建和维护一个实用且可扩展的控制后端，以实现大规模物联网，从而为我们的互联世界提供支持。
In this article, we introduce the concept of FoT, a paradigm for on-demand IoT. On-demand IoT is an IoT platform where heterogeneous connected things can be accessed and managed via a uniform platform based on real-time demands. Realizing such a platform faces challenges including heterogeneity, scalability, responsiveness, and robustness, due to the large-scale and complex nature of an IoT environment. The FoT paradigm features the incorporation of fog computing power, which empowers not only the IoT applications, but more importantly the scalable and efficient management of the system itself. FoT utilizes a flat-structured virtualization plane and a hierarchical control plane, both of which extend to the network edge and can be reconfigured in real time, to achieve various design goals. In addition to describing the detailed design of the FoT paradigm, we also highlight challenges and opportunities involved in the deployment, management, and operation of such an on-demand IoT platform. We hope this article can shed some light on how to build and maintain a practical and extensible control back-end to enable large-scale IoT that empowers our connected world.
