An Active Data Integration Model Based on P2P Routing Service

To provide more efficient and active data integration service in network manufacturing environment for cooperated enterprises, a 5-layered active data integration model was proposed. Core of the model are layer 2, 3 and 4, which separately defines the description of data resources, data routing service and active data exchange service. Data router which provides data routing service uses P2P technique to locate application nodes which possess resources required and select the optimal path to download the resources among original resource provider and the nodes having the designated resources. The data pump that provides active data exchange service uses XML-based and remote controlled data exchange technique to perform data syntax analysis and semantic check, and then draws data from local applications or loads data into the applications with data exchange specifications. With this model, the shared data resources may have more adaptability and activeness, resource transmission delay will be shortened, and the effect of data integration will be enhanced.
