Abstract:
   There can be M2M scenarios where responses from a server against
   requests from client are redundant. This kind of open-loop exchange
   (with no response path from the server to the client) may be desired
   to minimize resource consumption in constrained systems while
   updating a bulk of resources simultaneously, or updating a resource
   with a very high frequency. CoAP already provides a non-confirmable
   (NON) mode of message exchange where the server end-point does not
   respond with ACK. However, obeying the request/response semantics,
   the server end-point responds back with a status code indicating
   "the result of the attempt to understand and satisfy the request".

   This document introduces a header option for CoAP called 'No-
   Response'. Using this option the client can explicitly tell the
   server to suppress all responses against the particular request.
   This option also provides granular control to enable suppression of
   a particular class of response or a combination of response-classes.
   This option may be effective for both unicast and multicast
   requests. This document also discusses a few exemplary applications
   which benefit from this option.
