Background/Objectives: When an IoT service failure occurs, it is difficult to identify the source of the problem. In order to ensure stale IoT services, error causes need to be identified and the flow of interconnection services controlled. Methods/Statistical Analysis: Two types of requirements, namely, platform-device direct connections, and platform-device network connections, are specified for stable IoT services. A SDN based architecture using REST APIs that combines the analysis results in accordance with the requirements of both connection types is represented. Findings: In this paper, a method for providing stable IoT services was presented. The efficacy of the proposed method was verified via simulation using a floodlight SDN controller to the SDN adaptor of proposed architecture in a case study. Network errors and the causes of IOT service faults can be easily identified using our proposed architecture and API. Application/Improvements: The proposed architecture can be applied to manage errors in IoT services. Further, it can be used with a reference architecture to instantiate systems that provide stable IoT services.
