Aspect-Oriented Middleware In Real-Time System

Distributed real-time system software in size and complexity are increasing. Although the calculation of resources, processing capacity and network bandwidth has in the past decade, the magnitude of the growth of large-scale distributed real-time software systems tectonic remain very much. To solve these problems, a better approach is to use middleware. However middleware itself is becoming increasingly complex, particularly when dealing with cross-cutting nature of those concerns. Wide concerns, such as sustainability, the communication, safety, quality of service and can not easily be modular synchronous nature, and therefore there is a code in the system chaotic, which may lower the trusted middleware capabilities.At the same time, middleware software as an integral foundation has been with operating system, database go hand in hand, in the context of showing the world the rapid development momentum, has become a huge industry. The network world is open, and may grow volatile, distributed nature, autonomist, isomerization unit of information systems have become an inherent feature. Achieving integrated information systems integration has become a national informationization universal demand, and a direct reflection of the entire country informationization level middleware through interconnection, data integration, application integration, process interface, user interaction, etc., has become a large network of advanced applications, integration, deployment, operation and management of key support software. Therefore, the study of middleware has great significance.Software development-oriented aspects (AOSD) is the solution of large-scale system for the purpose of cross-cutting issues, the purpose of which we are linked to it and middleware for consideration. Through the application-oriented approach to middleware regard to the above, we can eliminate many problems inherent middleware, which improved the performance middleware, but also facilitate the construction of middleware. The middleware used for real-time systems-oriented aspects of treatment, is a good example.The first middleware research done a comprehensive summary of the status quo, including the concept and middleware products, middleware requirements and commercial middleware platform. Then introduced the technical aspects of software development, through to the technical aspects of the history and development of basic briefing on the Order of the readers have an overall grasp.Done in the way above, this would provide the context programming model middleware strategy done some highlighted, evaluated and compared, and then use the connection to the Construction middleware software development to the status of a number of useful discussions in this final, real-time systems to the middleware used to the methods and perspectives have done more in-depth analysis.
