Title : CoAP option for no server-response Author(s) : Abhijan Bhattacharyya Soma Bandyopadhyay Arpan Pal Filename : draft-tcs-coap-no-response-option-01.txt Pages : 10 Date : 2013-09-06 Abstract: The server end-point does not respond with acknowledgment (ACK) in non-confirmable (NON) mode of CoAP. However, the server responds the client with a status code indicating "the result of the attempt to understand and satisfy the request". But there may be typical scenarios, while updating resources in NON mode, where any kind of response from the server may be considered redundant. Thus, in this case, the transaction becomes completely open-loop with no reverse path from the server to the client. This kind of exchange may be useful in constrained systems looking for maximized throughput with minimized resource consumption. This draft introduces a header option: 'No-Resp' to suppress responses from the server and discusses an exemplary but practical use case which actually motivated this proposition based on real experience. This option not only allows suppressing any kind of responses but allows suppressing a typical class or a combination of classes of responses. This option is applicable for both request/ response as well as resource- observe mode and may be effective for both unicast and multicast scenarios.
