Service-Oriented Architecture for Next Generation, Large-Scale Accelerator Control Systems

Traditional frameworks for the development of accelerator control systems do not scale for the control of next-generation large ­scale accelerators, which will consist of many sub-accelerators and operation teams. This project will develop a reference Service-Oriented Architecture (SOA) that promotes multiple levels of loose coupling to increase the robustness and adaptability of overall control applications. In Phase I, key middleware technologies were surveyed and sample control system processes were implemented. It was determined that a SOA for control systems must integrate two separate service buses to provide the required capability. Phase II will involve the systematic implementation of the dual-bus SOA environment for accelerator control systems. The implementation will ensure vertical propagation of data from various low-level systems and horizontal data exchange between subsystems. A generic optimization framework will be developed to guide the overall design. Finally, several control applications will be developed, using the SOA environment to demonstrate the results. Commercial Applications and other Benefits as described by the awardee: In addition to the application to accelerator control, the SOA for control systems should find application to any large scale industrial control or mission-critical system, such as air tra¿c control and industrial manufacturing process control
