Abstract:
There can be typical M2M scenarios where responses from the data
sink to the data source against request/ notification from the
source might be considered redundant. This kind of open-loop
exchange (with no reverse path from the sink to the source) may be
desired while updating resources in constrained systems looking for
maximized throughput with minimized resource consumption. CoAP
already provides a non-confirmable (NON) mode of exchange where The
receiving end-point does not respond with ACK. However, the
receiving end-point responds the sender with a status code
indicating "the result of the attempt to understand and satisfy the
request".
This draft introduces a header option: 'No-Response' to suppress
responses from the receiver and discusses exemplary use cases which
motivated this proposition based on real experience. This option
also provides granularity by allowing suppression of a typical class
or a combination of classes of responses. This option may be
effective for both unicast and multicast scenarios.
