Abstract:
CoAP is a RESTful transfer protocol for constrained devices and
networks. It is anticipated that constrained devices will often
naturally operate in groups (e.g. in a building automation scenario
all lights in a given room may need to be switched on/off as a
group). This document provides guidance for how the CoAP protocol
should be used in a group communication context. An approach for
using CoAP on top of IP multicast is detailed for both constrained
and un-constrained networks. Also, various use cases and
corresponding protocol flows are provided to illustrate important
concepts. Finally, guidance is provided for deployment in various
network topologies.
