IoT Edge Challenges and Functions

Many IoT applications have requirements that cannot be met by the traditional Cloud (aka Cloud computing). These include time sensitivity, data volume, uplink cost, operation in the face of intermittent services, privacy and security. As a result, the IoT is driving the Internet toward Edge computing. This document outlines the requirements of the emerging IoT Edge and its challenges. It presents a snapshot of the state-of-the-art, a general model, and major components of the IoT Edge, with the goal to provide a common base for future discussions in T2TRG and other IETF WGs and RGs.
