Research And Design Of Middleware About Data Distributing In Campaign System

With the rapid development and wide use of high-tech in military, modern military information system for the efficient transmission of information have become increasingly demanding, and requires the ability to be stable in heterogeneous and harsh battlefield environments. The data between the workstation within the system, as well as the process of business applications interact with the operation of information systems, data exchange is usually complex information systems and difficult to manage in military information system. In order to improve the performance of the interconnected combat system applications and to keep real-time, reliable, safe and efficient transmission and distribution of data, we analyzed the distribution characteristics of the data-oriented combat system applications, combined with the characteristics of the air defense system to carry out the projectWe analyzed the status, the overall needs and functional requirements of data distribution software based on requirements on data distribution middleware on combat system and proposed a priority-based data distribution strategy and distribution model to transmit information according to priority of information. Designed the functional modules, middleware framework and interface, of middleware, and described the various components of the data distribution middleware and data distribution middleware agent, management software.Test results show that this middleware can meet the requirements of combat system, especially promote the efficiency and functionally.
