Abstract:
CoAP is a RESTful transfer protocol for constrained devices. 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
defines 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 causes and corresponding protocol flows are provided to
illustrate important concepts. Finally, guidance is provided for
deployment in various network topologies.
