PEER-TO-PEER EXCHANGE OF DATA RESOURCES IN A CONTROL SYSTEM |
摘要 |
System(s) and method(s) are provided for peer-to-peer exchange of data in a control system. Decentralized storage and multi-access paths provide complete sets of data without dependence on a specific or pre-defined data source or access paths. Data is characterized as data resources with disparate granularity. The control system includes a plurality of layers that act as logic units communicatively coupled through access network(s). Server(s) resides in a service layer, whereas client(s) associated with respective visualization terminal(s) are part of a visualization layer. Peer-to-peer distribution of data resource(s) can be based on available access network(s) resources and optimization of response time(s) in the control system. When client requests a data resource, all the locations of the data resource and the quickest source to retrieve it are automatically determined. The client stores copy of data resource. Peer-to-peer distribution of data resource(s) can be implemented within the service layer or the visualization layer.
