Title : Group Communication for CoAP
Authors : Akbar Rahman

Filename : draft-ietf-core-groupcomm-18.txt

Abstract:
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 document provides guidance for how
the CoAP protocol should be used in a group communication context.
An approach for using CoAP on top of IP multicast is detailed. Also,
various use cases and corresponding protocol flows are provided to
illustrate important concepts. Finally, guidance is provided for
deployment in various network topologies.
