Abstract:
   There can be M2M scenarios where responses from server against
   requests from client might be considered 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 simultaneously updating a bulk of
   resources 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 draft introduces a header option for CoAP called 'No-Response'.
   Using this option the client explicitly tells the server to suppress
   responses against the particular request. This option also provides
   granular control to enable suppression of a particular class or a
   combination of response-classes. This option may be effective for
   both unicast and multicast requests. Present draft also discusses
   few exemplary applications which benefit from this option.
