                 draft-hong-t2trg-iot-edge-computing-02

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 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.
