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 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.
