Abstract:
   The Constrained Application Protocol (CoAP) allows clients to
   "observe" resources at a server, and receive notifications as unicast
   responses upon changes of the resource state.  In some use cases,
   such as based on publish-subscribe, it would be convenient for the
   server to send a single notification addressed to all the clients
   observing a same target resource.  This document updates RFC7252 and
   RFC7641, and defines how a server sends observe notifications as
   response messages over multicast, synchronizing all the observers of
   a same resource on a same shared Token value.  Besides, this document
   defines how Group OSCORE can be used to protect multicast
   notifications end-to-end between the server and the observer clients.
