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.
