               A Data-centric Deployment Option for CoAP
                     draft-gundogan-core-icncoap-00

Abstract

   The information-centric networking (ICN) paradigm offers replication
   of autonomously verifiable content throughout a network, in which
   content is bound to names instead of hosts.  This has proven
   beneficial in particular for the constrained IoT.  Several
   approaches, the most prominent of which being Content-Centric
   Networking (CCNx) and Named-Data Networking (NDN), propose access to
   named content directly on the network layer.  Independently, the CoRe
   WG developed mechanisms that support autonomous content processing,
   on-path caching, and content object security using CoAP proxies and
   OSCORE.

   This document describes a data-centric deployment option using
   standard CoAP features to replicate information-centric properties
   and benefits to the host-centric IoT world.

1.  Introduction

   Information-Centric Networking (ICN) introduced the idea to turn
   named content objects into first class citizens of the Internet
   ecosystem.  This paradigm gave rise to (i) a decoupling of content
   from hosts and the ability of ubiquitous content caching without
   content delivery networks (CDNs), and (ii) serverless routing on
