Thread networking’s emergence as the de facto low-power IP networking technology warrants investigating a Thread interface within embedded operating system network stacks. Although there exist many embedded software platforms providing Thread integration, these examples notably lack multi-tenancy and a principled policy for interface design and resource sharing. This work first provides a survey of leading embedded operating systems’ networking and Thread capabilities followed by a proposed Thread networking interface design. To demonstrate the interface design, kernel Thread networking support was implemented within TockOS and provided functional interoperability for a Tock child device to attach to an OpenThread router.
