The diagram below shows the overall architecture of this blueprint. The colored components represent customizations or new implementations added for this blueprint. The details of the edge node and inter-edge data sharing are further illustrated below.
The Smart Data Transaction for CPS blueprint consists of the following types of node roles.
...
The diagram below illustrates the architecture for data sharing between two edge nodes. (The green and red lines show flows of data originating on the left and right nodes respectively.) The decision whether to share a piece of data and with which nodes is under the control of custom rules configured in the EdgeX Foundry rules engine service. The synchronization application picks up the data marked by the rules engine and forwards it to the appropriate edge node through the cluster network. The shared data is received by the device proxy service, which forwards it to the core data service where it can be processed as a regular event, including such processing as sending commands to local sensors based on the content of that event and configured rules.
