Abstract:
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 the CoAP protocol should be used in a group
communication context. An approach for using CoAP on top of IP
multicast is detailed based on both 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.
