Internet-Draft draft-ietf-core-groupcomm-bis-16.txt is now available. It is a
work item of the Constrained RESTful Environments (CORE) WG of the IETF.
Title: Group Communication for the Constrained Application Protocol (CoAP)
Authors: Esko Dijk

Name: draft-ietf-core-groupcomm-bis-16.txt
Pages: 117

Abstract:
The Constrained Application Protocol (CoAP) is a web transfer
protocol for constrained devices and constrained networks. In a
number of use cases, constrained devices 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
specifies the use of CoAP for group communication, including the use
of UDP/IP multicast as the default underlying data transport. Both
unsecured and secured CoAP group communication are specified.
Security is achieved by use of the Group Object Security for
Constrained RESTful Environments (Group OSCORE) protocol. The target
application area of this specification is any group communication use
cases that involve resource-constrained devices or networks that
support CoAP. This document replaces and obsoletes RFC 7390, while
it updates RFC 7252 and RFC 7641.
