                 Report from the Smart Object Workshop

Abstract

   This document provides an overview of a workshop held by the Internet
   Architecture Board (IAB) on 'Interconnecting Smart Objects with the
   Internet'.  The workshop took place in Prague on 25 March 2011.  The
   main goal of the workshop was to solicit feedback from the wider
   community on their experience with deploying IETF protocols in
   constrained environments.  This report summarizes the discussions and
   lists the conclusions and recommendations to the Internet Engineering
   Task Force (IETF) community.

   Note that this document is a report on the proceedings of the
   workshop.  The views and positions documented in this report are
   those of the workshop participants and do not necessarily reflect IAB
   views and positions.

1.  Introduction

   The Internet Architecture Board (IAB) holds occasional workshops
   designed to consider long-term issues and strategies for the Internet
   and to suggest future directions for the Internet architecture.  This
   long-term planning function of the IAB is complementary to the
   ongoing engineering efforts performed by working groups of the
   Internet Engineering Task Force (IETF), under the leadership of the
   Internet Engineering Steering Group (IESG) and area directorates.

   Today's Internet is experienced by users as a set of applications,
   such as email, instant messaging, and services on the Web.  While
   these applications do not require users to be present at the time of
   service execution, in many cases they are.  There are also
   substantial differences in performance among the various end devices,
   but in general end devices participating in the Internet are
   considered to have high performance.

   There are, however, a large number of deployed embedded devices, and
   there is substantial value in interconnecting them with the Internet.
   The term "Internet of Things" denotes a trend where a large number of
