   Group Communication for the Constrained Application Protocol (CoAP)


   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.
