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 Non-confirmable
(NON) messages that are not acknowledged by the recipient. However,
the request/response semantics still require the server to respond
with a status code indicating "the result of the attempt to
understand and satisfy the request".
This specification introduces a CoAP option 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.
