Development And Research In EPC Network Middleware Of Enterprise Information Interaction

With the modern logistics, the development of supply chain management, logistics, information exchange and transfer is becoming increasingly important. People have been thinking about how to achieve real-time information exchange and transfer, the United States in 1999 by the Massachusetts Institute of Technology Auto-ID Center Electronic Product Code (EPC, Electronic Product Code) a new concept. EPC system through the development of not only real-time tracking of goods, but also by optimizing the entire supply chain to provide support to users, thus promoting the automatic recognition of the rapid development of technology and be able to significantly improve the quality of life for consumers worldwide.Were a complete networking system is mainly composed by EPC tag, RIFD reader, ALE middleware, EPCIS middleware and middleware ONS. Complex networking goal is to form an open-loop nature of the global network structure, how to set up inter-firm network structures within the various business systems and networking system between the object of current research on how interaction has become a hot issue. ONS objects, as well as networking among EPCIS module is related to the interaction between the various applications of the core components, it is the connection between the enterprise information system hub.Through the Global Research Network EPC Global authority issued a series of norms and in-depth study on the current complex network of information exchange needs of enterprises fully understand that the study of key technologies in this field has caught the EPCIS event monitoring and handling events Subscribe query, event callback query operation, ONS resource locator server multi-level structures. The problem is one of the cores of the EPCIS server-side query operation, as well as how to ensure the realization of ONS query the safety of the credibility of the process.In strict accordance with the relevant norms, to complete all the EPCIS server-side development work based on type and form of middleware to improve and provide the corresponding jar binary Java packages and internal documents of the API can be easily carried out in the secondary development of middleware. The realization of the EPCIS server-side interface for all services, including monitoring mechanisms EPCIS events, the internal real-time query, query control, query callback modules, through a variety of ways the success of the release, enabling the client to facilitate the service call. The realization of the ONS core algorithm, the experiment was completed through the ONS set up multi-level server.ONS Analysis of the process is the credibility of the security and networking in the enterprise were the focus of the study information exchange and difficulty, through a variety of popular encryption algorithm encryption scheme and in-depth understanding and analysis, summed up a set of network security in the ONS encryption scheme. Through the current popular mode of network attack analysis, verify the security of the package. Through a large number of experiments and analysis of experimental data, from the efficiency point of view to verify the feasibility of this package.Middleware in the complex network developed on the basis of the demonstration system set up. Middleware for the enterprise based on the presentation material of the secondary development of networking systems, as well as all the objects of inter-firm information exchange between networked.
