Some of the capabilities offered by the IoT, e.g., capabilities for computing, storage and analytics, are evolving in closer proximity to the IoT data sources. This Recommendation provides an overview on related challenges faced by the IoT and describes how the IoT supporting edge computing may address these challenges. From the edge computing deployment perspective, service requirements for support of edge computing capabilities in the IoT are identified as well as related functional requirements. As example, scenarios of edge computing deployment in different application domains, edge computing scenarios for Vehicle-to-Everything and for smart manufacturing are provided in Appendix I.
