Mechanisms to support adaptive constrained application protocol (CoAP) streaming for Internet of Things (IoT) systems

摘要

The CoAP base protocol can be enhanced to support CoAP streaming. Streaming can use a reserved “/streaming” URI and current CoAP methods can be used towards the “/streaming” location, which will trigger or terminate streaming operations. Streaming can use a new STREAM method. Alternately, the current Observe mechanism can be enhanced to support streaming. Streaming operation can be combined with existing CoAP block transfer operations.
