These include time sensitivity, data volume, connectivity cost, operation in the face of intermittent services, privacy, and security. As a result, IoT is driving the Internet toward edge computing. This document outlines the requirements of the emerging IoT edge and its challenges. It presents a general model and major components of the IoT edge to provide a common basis for future discussions in the Thing-to-Thing Research Group (T2TRG) and other IRTF and IETF groups. This document is a product of the IRTF T2TRG.}, }
