Mass Configuration of Heterogeneous IIoT Nodes: A Proposal and Experimental Evaluation

Securely managing Internet of Things (IoT) devices is a fundamental challenge. Management protocols for IoT must be scalable and extensible, especially when dealing with device heterogeneity. Because of device resource limitations in IoT and the sheer size of such networks, traditional management protocols are not well- suited. In this paper, we propose our HTTP/3 publish-subscribe architecture to meet the ends of en masse device configuration, on-boarding, and monitoring. We compared our solution to industry-standard protocols by collecting data from real traffic in networks of up to 500 clients. We found our solution to excel in ease of use and performance, while having slightly higher CPU utilization compared to the other protocols.
