The Constrained Application Protocol (CoAP) is a specialized web
transfer protocol for constrained devices and constrained 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 specification defines how CoAP should be used in a group
communication context. An approach for using CoAP on top of IP
multicast is detailed based on existing CoAP functionality as well as
new features introduced in this specification. Also, various use
cases and corresponding protocol flows are provided to illustrate
important concepts. Finally, guidance is provided for deployment in
various network topologies.
This document is a product of the Constrained RESTful Environments Working
Group of the IETF.
