                   IoT Edge Challenges and Functions
                 draft-hong-t2trg-iot-edge-computing-04

Abstract

   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 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.
